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.
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 captured and tortured Nebula, using her as a bargaining tool to force Gamora to reveal the location of the Soul Stone. Nebula managed to escape and regrouped with the Guardians and the Avengers on Titan, during their battle against Thanos, before she realized that he killed Gamora to get the Stone.
Some time ago, Thanos killed Nebula's family and adopted her as a daughter, raising her to be a galactic warrior on his behalf. It is most likely that the Mad Titan had wiped out half her species, like he did with so many others, in his “noble” quest to bring balance to the universe.
Nebula's feelings on the death of Thanos are understandable, especially with the way Gillan broke it down in her quote. Despite his abusive nature, the Mad Titan was the only parent figure that the character has had for a long time.

Did Thanos cry when he killed Gamora?
He mourns." "What does this monster have to mourn?" The Sacrifice of Gamora was the ultimate step that was required in order for Thanos to obtain the Soul Stone. When Red Skull informed Thanos that he must sacrifice someoned that he loved to obtain the Soul Stone, Thanos tearfully threw Gamora off a cliff, killing her.
And OOOPS SURPRISE Thanos has to sacrifice "what he loves most" in order to get the stone. His tears imply that he loves Gamora, but in one of my favorite movie moments of all time, Gamora spits back at him, "This isn't love."
Nebula in the Marvel Cinematic Universe ultimately evolves from a villain to a true hero and a member of the Guardians of the Galaxy, while the character in Marvel Comics is depicted almost exclusively as a villain.
Thanos better appreciates Gamora, because he feels that her successes reflect upon him, as he raised and trained her. Conversely, Thanos does not show similar affection for Nebula.
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.
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.
This was part of a cosmic process by which the wielder of the Soul Stone had to sacrifice something they truly loved. Thanos killed Gamora regretfully, showing he would truly do anything to accomplish his goals, no matter how much it hurt him personally.
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.
He loved Gamora, but his goal was much bigger. He sacrificed his love to see a better universe. On the other hand, someone like Tony loved his daughter more than Thanos ever could.
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.
It turns out that Nebula star Karen Gillan very much believes that Nebula does have a little crush on Peter Quill, and during a recent interview with The New York Times, director James Gunn expanded on that a bit and believes that there could be something there.
McFeely: Nebula doesn't know about the exchange that's required at Vormir, no one knows. No one knows other than the people that were there. She only knows her sister didn't come back.
So much so that Tony was arguably the best father figure that Nebula has ever gotten in the MCU. Thanos had an abusive relationship with his adopted daughters. While he favored Gamora (Zoe Saldana), he was harsh and downright dismissive of Nebula.
But what we do know for sure is that Nebula is a Luphomoid. In the Marvel Cinematic Universe, Luphomoids are a humanoid race notable for having blue and/or purple colored skin. Although, Nebula had some of her limbs replaced with various robotic parts after getting severely injured while Thanos was training her.
Actually, Karej shaved her head of her own before Marvel could tell her that she didn't need to do so. Guess she opted to use prosthetics like Marvel planned in her later appearances to not have to shave her hair and costing her other roles. Karen had to wear a wig when she did "The Time of the Doctor," for Doctor Who.
3, Gamora's role is that of a variant from a different timeline who joins the Ravagers and doesn't remember her love with Peter Quill. The reason for her memory loss is that she is not the same Gamora from the previous films and never met the Guardians or went through character development [1].
Probably, the user may probably see the one he loves the most, or the one who was sacrificed for the Soul Stone. Gamora fulfills both the criteria. She was the one Thanos loved the most, also she was sacrificed for the Soul stone. Probably this is the reason Thanos saw her moments after the snap.
