Burden and guilt? [ One can almost hear the razor sharp smile in Verim's thoughts. ] That isn't my concern. He and cohorts assaulted Lady Vera and killed her. They used muters to strip her of her power and that of any other Blood nearby that might have helped her. What he did is inexcusable and deserving of justice. I carry no burden or guilt should his actions be without good reason, I've no issue with his execution.

[ Or carrying it out himself. ]

However, until we know the scope, determining the severity is impossible. If Vera had harmed him, his family, or threatened to harm him, then I cannot blame him for taking out that threat, only the cowardly manner in which he did it.
