Which is worse?

I noticed something that was very stupid (for purposes of this post, it doesn't matter what exactly that thing was). A coworker asked me "Do you think it was done by accident?" I figure either way, it's bad.

If yes, this stupid thing was done by accident, and that implies safety checks are missing, which is bad.

If no, it wasn't an accident, that implies it was thought out, and thus somebody with sufficient power to make things happen thought this stupid thing would actually be good.
