Well they have already been educated, that's why they go off like this, they think they're smart.

But they've been typically taught by others of their ilk, so you'd have to educate them again in the correct manner. They have to be re-educated, with all its worrying connotations.

At this point I think it's less morally ambiguous to just bludgeon them to death with a baseball bat. Call it evolution, survival of the least annoying.
