Halloween costumes

I have two Halloween parties to attend this weekend, one on Friday and the other on Saturday. I'm trying to get costume ideas, and I think I've got it! The only problem with it is that it could offend a lot of people. Would that be wrong, or should I continue my mantra of "if you're offended it's your fault for being so easily offended"?
Idea:
The Nocturnal Abortion

Background:
It's a combination of a supervillain from a webcomic a few years back and an idea someone had at the party this past weekend in Waltham. His idea was to take his pregnant wife with him and dress himself as a doctor with a coat hangar around his neck (with a fake fetus on the end, of course).

So, yeah, my idea is sort of a variant on all of it. It involves a bloody hook for the left hand, a surgeon's robe painted black with a red cape, a dust mask with some blood on it, and fake blood all over the hook and left forearm. There would also, most likely, be a fake fetus on the end of the hook.

Question: Too much?
