I don't think Momonga was so paranoid and so ruthless? Of course, he was meek and afraid of many things, but not to that extent for at least in the beginning. Although what he started doing later on was truly disgusting, so whatever. I also might just not remember good.
Momonga is acting Top paranoid. I'm not saying it's unnecessary but it's uncharacteristic of Momonga to be this cunning and scheming at the beginning. Well there are infinite realities and maybe this a reality where Mononga is more ruthless and less benevolent when he was human.
