Nope, the very definition of wrath is that I'd use such passion and violence in order to kill you (i.e. beat you to death, or stick you with a knife), which obviously I'm too lazy to face the consequenses of. Assasination on the other hand (which would involve a lot more planning, but lead to a better outcome) would leave it so that there's no way I'm implicated and it would be the execution that would lead to your death, as apposed to your death lead to me doing a bunch of crap I don't want to do.
In other words, in pure wrath, the end doesn't justify the means as much as it does in assasination, which is really more of an artform and would require little wrath.
So... I'd still have someone test your food.
