why did omni man beat his son

It could be due to his own psychological problems.

Yes, Omni Man can be considered evil in the comics. His actions and motives often go against moral and ethical standards.

Maybe it's for a greater cause or to save many others. Sometimes in extreme situations, characters make tough choices.
