How do you feel about me tearing off the wings of a butterfly with my bare hands?
Did you have a reason for that?
No, I just don't like butterflies.
It is wrong to injure animals. Serial killers start out torturing animals before they move on to people.
What does it matter? I like killing animals and butterflies are annoying. Their wings are pretty though.
What you're doing to animals, even if they are bugs is really wrong. I would highly recommend you seek therapy to try to get you out of this destructive mentality you have towards animals.
