Don’t judge people upon their appearances or their actions. Who are you to determine what is normal and what is just. People that may be strange or abnormal could be a personable and sociable person. And to people who do bad or uncivilized actions, purposeful or not, should not be tied down and shunned for what they have done. Overlook and forgive their follies and comfort them. In the end it will create more peace than war. Now this is for the exception of people who are truly evil. Ones who deliberately hurt, kill, or otherwise be a hinderance to humanity should be avoided, forgiven but avoided. You do not want the influence of evil or darkness affecting you in the end, or otherwise influencing you to follow or mimic their actions and becoming wicked yourself.
