I never understood why some people find comfort in attacking other's character. If hurting someone is your only way of coping, then you need to reassess a few things in you life. Does how you act align with your morals? Or are your morals just to bedazzle your otherwise decrepit character? I am not the perfect being nor claim to have never done all these things, but I do actively try to check myself to ensure mistakes like this don't happen again. The guilt of hurting people is probably one of the worst things you can feel. Well... one of the worst things you should feel.

How can someone expect you to treat others with kindness if you can't treat yourself with kindness?
