But in the movies its established that Thanos himself is the one who killed the Zehoberei giving their relationship an intense and complex twist with an icky undercurrent of emotional abuse.

Why did thanos cry when he killed gamora. Notwithstanding the world of hurt Nebula had to endure throughout her life with the installation of her cybernetic enhancements her torture at the hands of Thanos in Infinity War was doubly painful in that it also scarred her sister Gamora. But then he suddenly resurrects and captures Gamora. The dynamic between Thanos Josh Brolin and Gamora Zoe Saldana was one of the main story arcs of Avengers.

My guess as to the cause of his favoritism of her would be that she was both the first one he adopted and because of how fearless and strong she seemed as a child. And whats more he was visibly crying when he had to kill her in Infinity War. Despite his reluctance and her frantic screams Thanos threw Gamora off the cliff to her death.

While he had a number of sycophants and hangers on Thanos had no one that he viewed or treated as an equal and whether he realized it or not his favor was lavished specifically on those that he viewed as a reflection of the traits in himself that he. His method of torture is pretty gruesome and uses Nebulas physiology against her. By far the worse thing Thanos has ever done to Nebula and Gamora has been to torture and kill them respectively.

Thanos tells Peter to kill Gamora but when Peter decides to pull the trigger a flurry of bubbles leaves his gun in lieu of a energy blast. But exactly what Thanos intends for her isnt clear since his idea of mercy is up for debate kill her quick or leave her alive. On a dead world.

She visibly goes into shock when Thanos turns to her crying and realizes that his loved one is her. As the Red Skull revealed the Soul Stone can only be retrieved by someone sacrificing something they love and contrary to Gamoras belief Thanos truly did love her albeit in a twisted way. In his mind it probably reminded him of himself and it gave him hope that someone might be able to truly understand his reasons for what he does and that.

Gamora placed the Power Stone in the hilt of her sword and used it to kill Thanos and has now come to gather the other Infinity Stones to retrieve the piece of her soul that is still trapped inside of the Soul Stone. While Gamora keeps crying. While we were led to believe that Thanos was placing her in a dangerous situation I dont believe that he would have ever allowed any harm to befall her.
