It just seemed strange to me.

This version of Omni-Man isn’t even remotely like the one that massacred a gargantuan number of people without remorse and savagely beat his son to a bloody pulp, almost killing him.

Why is this version of Omni-Man so much more compassionate than the one at the end of S1, even crying over lesser life-forms, while he was perfectly content with massacring a bunch at the end of S1?

Why does he feel remorse for what he did on Earth when he didn’t initially?
