Viral is a tragic villain though.
After massacring untold humans for a millennia(and being created for the basis that it's his sole purpose, not born, fucking created).
Some random kids show up and rekt his shit and still his crown (literally) and than kill everything he knows.
He is now immortal and completely alone for the most part as he is deeply hated by most the characters, realizing the error of his ways he actually tries to help humans.
He is than taken prisoner and forced to pilot TTGL as he is one of the only competent pilots on the entire world (most pilots not having an ounce of actual skill, but just riding out their abilities because they have spiral energy).
I conclude he is than put to sleep by the anti-spirals and we get to see what Viral actually dreams about.
A family, having a wife and a daughter. He smiles sadly at his daughter and looks up at the sky where he sees Simon (empowered by Kamina's will) and realizes it's a sad dream, that will never come to be.
We get his devilish grin and he wakes up truly as one of the heroes.
Personally Viral was the only character in the entire show I felt anything for.
He is an actual good person.
