This could also be used to
describe certain people that do
stupid things that
endanger others. The ones that if there were
more like them, there would be more
accidents,
disasters, and the like.
For example, people who drink and drive - the more there are, the more car accidents, the more deaths. Or presidents who sell arms to other countries. Or people who have problems with road rage
The people who we really wish would off themselves in a manner that affects nobody else, before they do harm someone else.
