The problem i have is that the mc should’ve already been a cold blooded and efficent killer based on his experiences in conquering worlds. (Like the dude goes straight for the leaders and directly beats them to conquer the world) So him realizing that he should defeat opponents faster after witnessing how taking his time can cause tons of casualties is redundant since he should’ve been trying to defeat then fast and efficiently looking at past precedent. It’s fine to show that he’s developing compassion and guilt to those he looks as inferiors but to me this situation doesn’t feel like it works for that character development since none of this would’ve happened if it wasn’t for plot convenience.
