op is talking about sociopathic behaviour against the disenfranchised. as disagreeable the behaviour of the homeless might be, only people who themselves deserve to be given a lethal injection would actively seek to harass those they perceive as weak or homeless, with acts such as feeding them human shit or poison hidden inside food, setting them on fire or peeing on them while they sleep, stealing their meager belongings, etc which you see all the time on social media.
