I forgive him. Dude was raised by genocidal maniacs. It’s literally ingrained into his psyche. Morals dont just appear when you’re born. You learn them from those around you. Being on earth for roughly 20 years or so isn’t going to change that, especially for a guy who will live to be thousands of years old.

His time on earth made him doubt, but it wasn’t enough to fully break the indoctrination of Viltrum. Deep down he actually liked being Omni man, and he likes saving people.

So yeah I can forgive him. It’d be different if he changes and then goes back to being pro Viltrum.
