Psychologically speaking--in this scenario that didn't even happen IRL to a nonexistent son of a nonexistent god--Jesus' death experience would be much less damaging than it would have been to a normal human.
He knew the outcome was not only resurrection, but everlasting life ruling the universe. When I say "knew", I mean he really knew it--not in the sense most believers "know" Heaven is real. He really saw it with his own eyes.
He also knew at any moment he had the power to stop his own suffering.
