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.
Undaunted by The Other's death and Ronan's complaints, Thanos turned Ronan away, instructing him to return to his task and correct Gamora's betrayal, hiding his regret and only appearing slightly annoyed. Thanos then instructed Nebula to take up Gamora's place.
Starlin's answer means that Thanos didn't really have to snap to activate Infinity Stones as they react to the wielder's mental commands, but for the purpose of storytelling, he wanted a visual representation of what he's doing with the crystals.
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.

Why was Thor so weak against Thanos?
Another prevalent argument is that the God of Thunder was simply too exhausted at that point, having used all of his energy fighting Hela in Thor: Ragnarok.
Thanos wasn't a would-be god who sacrificed trillions for the sake of love, he was a cosmic villain who killed all those life forms for no other reason than because he could, and he wanted Uatu to watch. And it was for this dark reason that Thanos made the Watcher immune to his Infinity Snap.
On Earth, the Snap led to a five-year period in which the world fell into societal collapse and many countries abandoned their national borders. In 2023, the victims of the Snap were resurrected by the Avengers, after they went back in time to alternate timelines to acquire their own set of Infinity Stones.
According to the Eternals, the Hulk's snap released so much energy it was able to cause a mysterious cosmic event called an "Emergence," while Thanos' did not. It seems the Hulk's strength should not be underestimated, because his feat was much more impressive than Thanos'.
When Gamora finally does confront Thanos, she believes for a moment that she's killed him and breaks down, crying. An orange light passes over her--but it's fleeting. Whatever love Gamora has for Thanos is all but smothered by darkness.
We know that Gamora wasn't at Tony Stark's funeral - unsurprising considering that she didn't know him, really - so she must have fled after the battle was won.
As the entity reveals to Thanos that their energies merged when he was resurrected, creating an offspring called the Rot. Death and Thanos work together to destroy their offspring, and it is at this time that Death finally addresses Thanos and admits to feeling "love" for him.
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.
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.
The Hulk saw an alternate reality when he snapped his fingers: In the first vision, the Hulk saw the Russo brothers logically following the battle arena theme from Ragnarock into Infinity War and Endgame.
What would actually happen if Thanos snapped in real life?
The erasure of half of the population of ALL populations means that the ecosystems of earth will start collapsing all over the world. This is not a world ending event, and indeed, from a paleontologists view from the future, it will be impossible to see what exactly happened.
Originally Answered: Why are the original Avengers alive after the "Thanos snap"? Do you want the in-story reason or the out of story reason? In-story, it was luck. Everyone had a 50% chance of surviving the snap, and our main characters happened to get lucky.
The Time Heist in Avengers: Endgame allowed the surviving heroes to get the Infinity Stones and with the help of a Nano Gauntlet developed by Tony Stark, Bruce Banner, and Rocket Raccoon, Smart Hulk undid Thanos' snap.
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."
The spell was permanent, making it so Loki only reverted to having blue skin when touching a Frost Giant or one of their artifacts. Since Loki's appearance was a spell, not just an illusion, it could not be broken or reversed by Odin's death.
Creation of a branched reality: When Loki escapes with the Tesseract, he creates a branched reality, according to the Russo Brothers, the directors of Avengers: Endgame. This means that a new timeline is created where Loki is still alive [3].
