So, is the butler meant to be following the MC around, and is instead giving false reports? If the father thought he was lying, then the obvious action would be to have him followed, but since the father talks about how horrible it is to attack innocents while attacking the innocent MC and nobody bats an eye at that, it suggests someone trusted is telling them all the MC did do it. Mom claimed daddy actually liked MC, but there is zero anything to suggest that; beating the crap out of him and trying to send him on a villain arc is not any form of love.
