"Thanos' skin is almost impenetrable, we don't know whether Doctor Strange had the capability to do it," Russo said. "If he failed to cut it on time, Thanos would still able to do the snap. Doctor Strange realized this issue during his millions of test runs."
Because gauntlet was exactly made for his hand. he wasn't completely out (we can't even call it sleeping) and he didn't loosen his hand. mantis only stopped him he didn't completely lose his consciousness (mantis said thanos was mourning). Taking off the Glove on sleeping human still requires some level of strength.
Originally Answered: In Infinity War, when Tony and Co. had Thanos asleep, instead of trying to remove the gauntlet, why didn't they just kill him? Because of Mantis. Blasting Thanos with a unibeam, would risk injuring Mantis. Thanos is highly durable, so no telling anything they did use would harm him.
The primary reason was that Avengers could steal it through various means and reverse the snap. The second reason was that Thanos realized that no one should have that kind of power, not even himself. After snapping half of Universe's life, he retired to a life of a simple farmer because he already had everything.
Panels has superhuman strength and agility. On titan, when Iron Man was fighting thanos, he had to hit him with a lot of force (and I mean a lot of force) to get him to drop one drop of blood. So, technically, a bullet, or more specifically a lead one made by humans, wouldn't even penetrate his skin.
Powers and abilities
He can manipulate matter and live indefinitely without food, air or water, cannot die of old age, is immune to all terrestrial diseases, and has high resistance to psychic assaults. Thanos is also an accomplished hand-to-hand combatant, having been trained in the art of war on Titan.

After Tony snaps his fingers while wearing the Iron Gauntlet, he's transported to a mysterious place. As he tries to gather what's going on, he hears a voice call out to him. Tony turns around to see a grown-up version of Morgan, played by Langford. Tony quickly realizes the young woman is his daughter.
As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
Thanos definitely had everything planned and made a smart decision when he destroyed the Stones, as he not only saved himself from the temptation of keep using the power of the Stones but also saved himself from a potential curse like that of Red Skull.
His solution was simple, fair and brutal: He would kill half the population by random drawing. The rich and poor alike would be killed according to chance, and the rest of the population would have a chance to live in a world of plenty. The other Titans didn't go with his plan.
Thanos vs MCU Hulk
The polished fighting style of Thanos proved too much for Hulk and his overall brutality and savagery. Hulk had the upper hand for all of two seconds due to the element of surprise before Thanos was able to finish the fight with a few quick blows.
Soon after, we learn that before it was destroyed, Thanos went to the leaders of Titan with his idea: Kill half the people on the planet, but choose them randomly and dispassionately (rather than by ethnic or class lines, for example), to save everyone else.
In an interview with Cinema Blend, the director said that since Eternals are synthetic beings who cannot be killed, their necks were saved during the massive snap by Thanos.
Imagine, Tony survived after End Game, he could have his own replicated Pym particles, had a time machine in his suit and even had access to each timeline in the multiverse. Dr. Strange believed if Tony Stark survived then sooner he will be the most powerful being in the universe.
Perhaps the most plot-important after-credits scene in the Marvel Cinematic Universe was Ant-Man getting stuck in the Quantum Realm during the Snap.
In 2018, Jones was a victim of the Snap. Five years later, Jones was restored to life in the Blip.
In Avengers: Infinity War, the Thanos who was on the hunt for infinity stones said that he respects Tony Stark. In Avengers: Endgame, Iron Man (Robert Downey Jr) killed Thanos (Josh Brolin) by snapping his fingers when he wielded the infinity gauntlet.

At the end of the war, Tony Stark falls into a coma while fighting Captain Marvel, spurring Riri into continuing his legacy as a hero. With the help of an AI duplicate of Stark, Riri designs an improved suit of armor and takes on the name of Ironheart.
The main argument against Tony's worthiness of Mjolnir post-Endgame is all about how self-sacrifice doesn't mean being worthy of the hammer – Tony had already been close to death in order to save the world before he tried to lift the hammer in Age of Ultron, so self-sacrifice wasn't an immediate pass to being worthy of ...
stark's death is an absolute point. in every single universe. Because we know that Kang runs the TVA, and he basically keeps every single universe in check. by protecting the sacred timeline.
