I snatched the large bunch of beautiful flowers from the young girl who had a broken heart
Why would you take her flowers if she was already hurting?
I just felt like doing it. I really had no remorse for her and really wanted the flowers.
That poor girl have just had her heart broken, and you've compounded that by stealing her beautiful flowers and that makes you a really bad person. I don't think I want to be friends with you anymore, and if you want to rethink your choices in life, I would suggest that you say sorry to that girl and bring her back her flowers and try to maybe amend her heart just a little bit slightly if you can.
Does it make me crazy for doing this?
It does not make you crazy, in fact it makes you looks like a caring human being. If you steal things from others, you should try to make it right.
