Completely disagree
1- he is not killing just anyone, I asume you saw the 'experiments'
2- there was a sneak peek of what the future was before restarting and is a MAJOR difference to what he is doing
3- he is not commanding anyone, acting like a god or taking credit. Literally the one guy that 'saved the world' is dead to the world
So no, this is nof hypocritical
making him keep his powers was completely uneccessary, it would've been a better ending for everyone to be powerless and not have the mc keep his mumbo jumbo. he basically just went against his own principles. his whole battle against sejun revolved around how sejun wanted to dominate the world while maintaining his powers. he's doing just that.
unless this is the point they wanted to make with the ending of this manhwa, they ruined it.
