I suggest that you read the LN. It's quite a solid read. Spoiler: Volume 8 In a war with the kingdom, he kills over 20,000 soldiers single-handedly just because he wanted to try out a new magic spell.
how about God and Devil World mc starts out as a likeable guy but becomes an absolute asshat later on i dislike it because of this but maybe you want it
ew, the anime is disgusting imo the LN of Overlord is one of my all time favorite, just read the prologue and you will realise how good the writing is and yea at first I also thought that he is still kind cuz he was human but nah, he could not careless about hundred of thousands of people dying if it is for Nazarick, he care a lot about the NPC and his subordinate but for other, if they could be used then use them, if not then whatever, he just dont give a shit, also although he is pragmatic, it does not mean he is just do whatever he want and use anyone, he has his own rule, like if he receive someting he will pay them back etc, and he has his priority straight, overall I fcking love Overlord LN, highly recommended
