Sometimes I'll watch people trick the homeless just because it is so entertaining.
How could you be entertained by such cruel acts?
I think it is funny when the homeless are tricked
Homeless people are vulnerable and need help. You are being mean and cruel by enjoying when others play tricks on the homeless. You should spend more of your efforts helping those less fortunate.
They are a good source of entertainment
You should instead find entertainment in helping the poor rather than harming them. Would you not feel better to be friendly instead of harmful?
