My disappointment is Immeasurable and my day is ruined

my god MC is so annoying. He's literally your typical uke protagonist that yells, acts like a child and can't have a normal social interaction.

This work lacks everything. MC has no background and because he has nothing at all you don't care if he wins or loses. There's no point here like what the main goal? Why MC wants to evolve? Why MC is fine with killing? Why MC doesn't even question why this is happening and straight up go for killing? Why MC just did that? All these questions and no answer and no time to explain. This work hate questions so much that they replaced all questions and reasons with action like "MC goes and destroys"
