The most charismatic anti-hero.

And what’s wrong with Archibald sending his undead armies to attack? Besides, it’s still better to deprive someone of their sense of time than to execute them or leave their own brother to rot in prison.

Archibald didn’t rethink anything; he simply reconciled with his brother and, in the process, helped save the world. Besides, I’m sure that if it weren’t for the 3DO’s idea (and I’m sure it wasn’t NWC’s idea) to destroy Enroth, we would still be hearing about Archibald’s deeds, even if they weren’t directed against his brother.
