I'm going to hit the snail on the head with a hammer.
Why do you want hurt the snail? Did it do something to you?
It's so annoying, it is going so slow.
I'm sure that snail hasn't actually done anything wrong. You're just annoyed that it's there and that's not a reason to want to hurt it. You should never hurt an animal without having a good reason for it.
Okay you don't need to yell at me, I don't want hurt the snail.
That's good, I am glad you've realized that harming an innocent creature is wrong.
