Normally I really enjoy protagonists who are bastards so his actual personality doesn't bother me but the trick to writing these characters is that it has to feel like they genuinely deserve what they gain. The only thing it feels like he actually earned is his job (which he didn't even want) and in every other scenario he just gets lucky. I get that's kinda the premise but it means that the character doesn't really have any redeemable qualities and it's hard for the reader to not hate him. For a similar comic with a jerkish protagonist that handles this better I recommend "Worn and torn newbie".
