I mean. I think any of them could be driven to.

Just as anyone could under the right circumstances.

But under normal, every day circumstances?

Miriam: Not a chance. She wouldn't hurt a fly. Well maybe a fly. But stabbing isn't in her daily routine.

Drake: Yes, but probably by accident. He's more of a fighter than he thinks, but that isn't saying much and if attacked, he's more likely to shoot or smash someone in the face with his military grade ultra rugged tablet.

Knives are tools, not for stabbing

Alexis: Absolutely and for no reason.

Darius: He could but he'd rather not resort to such a crude and messy tactic when he can magic.

Zeki: Not a fighter, no, would not stab. (though again, anyone can be pushed to it and she can snap pretty bad)
