I see your point but I also see it as a different narrative structure.

Stiles killed truly by accident but he was in a direct confrontation with the individual he killed and did seem to want to hurt him if only to get his attacker to stop hurting him.

Lydia is like a natural disaster brought on by the mad scientist. He created the situation that led to his own destruction. Lydia played no conscious role in his death. Her feelings will be regret for losing control and fear it might happen again. I think that puts the character in a different place emotionally than Stiles.
