Lots of self centered emotionally driven actions and decisions most often leads to counter productive results though, so I don't know you can justify someone making things worse as not being his fault.

I also think you are speaking for other people with whom you seem to have no connection too. Maybe you think they're just voting for Trump, because they like his promess of bringing jobs back, or maybe, they're voting for him cause they want Iranians out of their country based on pure racism.
