yep it shows that despite becoming a monster in the eyes of most and changing like no one would believe he is still human inside and that's what counts
actualy thats more or less the theme of this manhwa power, money, influence, potential, ability all that maybe necessary for a lot of things but at the end of the day why and how you use it depends on whats inside you and thus also decides what result you get
well according to the story all the monarchs are stuck in an endless loop of war and while all those worlds were different they had two things in common "kill all the humans" and disdain for life besides your own and thats also where our mc is different from them
while his action may not be much different from fighting "to conquer" and "to win" his motivation is actualy "to protect"
