The reason that Michael didn't hurt Kay is simply that while cold-blooded, he is not a psychotic. Hyman Roth had tried to kill him. Frank Pentangeli had mistakenly betrayed Michael and intended to testify against him.
Michael and Kay tour Sicily together, during which Michael asks for Kay's forgiveness. Kay admits she will always love him, and they begin to rekindle their relationship.
By The Godfather Part II, Kay has decided that Michael is a cold, distant, inattentive husband and father, but only after an attempt is made on his life in the family home does she resolve to rebel against him.
At the very end of the movie, Michael lies to his wife, Kay, about having Carlo killed. This shows that he's set his course: she won't be able to be a part of his real world and will be shut out from seeing his true, ruthless nature in action.
Al Pacino said that Michael loved Kay from the beginning. Remember that Mario's character of Michael was a man who had dreams and I do not ever want to dismiss this important deep aspect of Michael.

Did Kay ever know about Apollonia?
Kay did not know. In the Movie, Michael tracks Kay down after he has been back for several years. In the movie Kay does not know. In the book Kay does not know.
Michael has become a true Corleone (embracing both Italian culture and mob affiliation), and his marriage to Apollonia signifies Michael's official acceptance of this change and what it means for his future. When Michael marries Apollonia, he is wedding himself not just to her, but to Sicily and his father's values.
However, when his father is nearly assassinated in late 1945, he is thrust back into the world he has avoided for so long. Reaffirming his loyalty at his father's bedside, Michael volunteers to kill both the men responsible: the drug kingpin Virgil Sollozzo and corrupt police captain Mark McCluskey.
She still loved Michael. She called Mama Corleone and came over to his place. Michael mentioned he was only glad to see Kay and his father out of his entire family. He also confessed to her he slept with another woman in Sicily!
Michael, under the belief that she miscarried, tries to convince her to stay, promising that he would change, but Kay is unwilling to listen and finally reveals the truth to him – her "miscarriage" was really an abortion. Enraged, he hits her across the face; the two are soon after divorced.
He is also mentioned many times throughout the film; the dialogue makes it clear that Michael is tormented with guilt over ordering his brother's death, and that it has alienated him from his ex-wife, Kay (Diane Keaton), and his son, Anthony (Franc D'Ambrosio), both of whom know the truth about Fredo's death.
A rat is another word for snitch or informant. These four rats betrayed the Corleone family: Salvatore “Sal” Tessio, Paulie Gatto, Fabrizio and Carlo Rizzi.
The Godfather. Born in 1925, Connie is the youngest child and only daughter of Mafia don Vito Corleone and his wife Carmela. She is the sister of Sonny, Fredo and Michael Corleone and adoptive sister of Tom. In 1945, she marries Sonny's friend Carlo Rizzi.
At the Long Beach Causeway toll plaza, Barzini's men trap Sonny and shoot him to death. During a meeting with the other crime family dons to establish peace, Vito realizes that Barzini masterminded Sonny's murder. After Michael returns from Sicily, he assumes Sonny's place as Vito's heir apparent.
There are a few different theories about why Michael Corleone never remarried or had more children after he left Kay in The Godfather Part II. Some people believe that he was still in love with Kay and never got over her.
Even when they walk together and she briefly stumbles, Michael catching her can be seen as a metaphor for exercising control. Later, in The Godfather Part III, Michael has a flashback about Apollonia. While he states that he loved her, it isn't clear if that is actually an honest admission.
In The Godfather II, Vito Corleone chooses his younger son, Michael, instead of his older son, Fredo, as his successor. This decision is based on Michael's intelligence and ability.
After Apollonia's death, Michael returns to the United States and marries Kay Adams, though she is unaware that he had been married, then made a widower while he was living in Sicily. Despite initially maintaining a steady marriage with Kay, Michael's heart truly remained with Apollonia.
Fredo's decision to betray his brother Michael and pass information about him to Hyman Roth is likely driven by resentment towards Michael for being chosen as the family's successor.
Ailment. In the first two movies, there are hints that Michael Corleone is concerned about a certain aspect of his health since he insists on drinking only water. In the third movie, it's confirmed that the Don has Diabetes.
The punch to Michael's face broke his cheek bone which gave him a permanent black eye (and caused his sinuses to continually run - hence the use of a handkerchief all the time) until he got back to America and had surgery to fix it (Freddie says, "that doctor did a good job.")
Toward the end of the film, Michael names Vincent as his successor, on condition that he break off his relationship with Mary. After her brother's debut concert, the assassin Mosca tries to kill Michael. One bullet grazes Michael's shoulder, but the other accidentally hits Mary in the chest, fatally wounding her.
The marriage, however, has made Michael's presence there known to the Corleone Family's enemies. Necessary precaution restricts the couple inside the villa's walls, but Michael relishes his days as a newlywed and spends the time teaching Apollonia English and instructing her to drive a car.
The kiss is known as "Il bacio della morte," meaning "the kiss of death." In this instance, it was to signify to Fredo that he was marked for death for betraying his brother to Hyman Roth (Lee Strasberg) and his right-hand man Johnny Ola (Dominic Chianese) in The Godfather Part II.
