I killed a snail and feel bad about it.
Why does it make you feel bad?
He was so cute and helpless. it makes me feel bad to think about his wife and children
Hurting animals is bad. Unless you did it on purpose there's no point in feeling guilty about it.
I wish I could apologize to his family.
You are right to feel bad about a hurt animal but hurting a snail on accident is not something you need to feel is your fault. It is normal for those things to happen sometimes.
