As proven by Thanos sacrificing Gamora, he's a being capable of love. While he may not have had affection for Nebula in her adult years, her growth and ability to fight with 100 percent of herself every time were enough for him to pay attention to her and try and "help" her to ensure she never lost again.
Thanos' love for Death takes on a new layer of meaning, as he continues to choose Death despite other options in the afterlife, making him appear almost cowardly. The Resurrection of Magneto #1 provides a fresh perspective on Thanos' obsession with Death and adds depth to the character's motivations.
The viewers believed Thanos loved one of his daughters and hated the other, but the reality was they were both victims of his wrongful utilitarian affection. This misconception could be due to the nature of physical abuse being more apparent than emotional abuse.
Since Gamora was most regularly successful in advancing his ideals and vision for the universe going forward, he favored her, equating her successes with love.
Omnipotent(ial) Thanos is immensely strong and resistant to injury, invulnerable to nearly all types of poison, disease, and telepathic attack. He also has incredible psychic abilities; he can sense things several star systems away.

Who can crush Thanos?
While audiences never got to see Quicksilver at full power, super-speed is one of the best abilities a hero can have when facing an enemy like Thanos. With enough training, Quicksilver would have been more than capable of defeating Thanos when he finally arrived in Infinity War.
However, Red Skull saw his true intentions, informing Gamora that Thanos was, in fact, weeping for Gamora, as he truly loved her as a daughter, and was heartbroken that he had to sacrifice her to get the Soul Stone. Disbelieving, Gamora could not comprehend that Thanos ever showed genuine love for her.
Thanos never cared much for Nebula, even going so far as to say in Guardians of the Galaxy that Gamora was his favorite. That could be because, to Thanos, Nebula was nothing more than a means to spare Gamora while still obtaining the Soul Stone.
Over the years, Gamora became Thanos' favorite child, and he considered her the future heir to his throne, which only strengthened the growing wedge in her relationship with Nebula and in time, Gamora built up the reputation as the "deadliest woman in the galaxy" and became well known throughout the cosmos.
Death is predominantly depicted as a skeleton cloaked in a black or purple robe, and at times appears as a Caucasian human female. A storyline in the title Captain Marvel showcases Thanos' scheme to conquer the universe, as the character becomes determined to prove his love for Death by destroying all life.
Thanos eventually realizes that all the trouble he went for in the snap: Killing Gamora, Killing Asgard's population, and ruining lives, have been for nothing. Thanos commits to finding a solution to reverse the snap. He starts to repair the gauntlet and confronts the Avengers.
But the one being Thanos hates more than anyone is the Merc With A Mouth himself, Deadpool – a rivalry that MCU fans are likely going to miss. While many fans may not expect this rivalry, Thanos and Deadpool have been at odds for quite some time.
Thanos is known in Marvel Comics for his everlasting love of Lady Death, but the object of the Mad Titans' desire was originally intended to be a member of the shape-shifting Skrull race.
Over time, Nebula developed an obsessive need to best Gamora in combat, but every time she lost, Thanos subjected her to torturous mutilation, replacing parts of her body with cybernetic enhancements.
Because she does not have a history with the Guardians, she does not reunite with them at the end of Endgame. Instead, she starts her own journey while Peter Quill is left mourning his dead girlfriend despite the existence of another version of Gamora in his universe.
The villain in Marvel Cinematic Universe (MCU) is the strongest villain that Avengers have ever face. He's the son of Alars, a Titans, which considered as the strongest race, just like gods. But who would have thought if Thanos in MCU is thousand years old! His age even surpasses Thor, the god of thunder himself.
While Steve Rogers gets the title of the oldest human avenger, Thor Odinson, as the mighty Asgardian God of Thunder, has a much longer life span than any of his Earth-born friends.
