The MC's okay for me I guess...aside for the fact that he's too self depreciating. Just...argh...be happy already! The fact that

Spoiler for to sum up OP MC and his downside troubles:

just because he wanted a little bit of power to help out in the activities of the village he got tricked and was turned into a vessel for an evil god. As a result he killed everyone in the village he was trying to help. (the sole reason why he feels he does not have the right to be happy.)

Even if the Sister used her life in exchange for a restraint that would help control the god but that being said his godly powers will leak out when he displays a great amount of emotion/weakness. Which in turn makes him even more gloomy because he might go on a rampage again. As a result he has a fear of making friends or being close to anyone.

On top of that he had a duty in the form of the vigilante Masquerade pushed onto him by someone else. Using that power he goes around threatening and interrogating bad people and to round it all up he's desperate to find a way back to his world.

Ahhh...but on Earth he's probably (almost) invincibru~ There's his modus operandi of flattening/torturing/threatening people only to the extent of not killing them. Yet letting them go if they apologize/atone. (there's no 'bad guys have to die for the sake of resolving the issue or i need resolve to kill people' stuff here)
