By being what they are.
The soul is not bad or evil. It is pure and there can really be no label for it.
Besides, we all have our own definitions for good, bad, nice, ugly, evil! But do we really know who is right? Have we found the ultimate truth yet? Everyone believes in what they believe, and who is correct no one really knows!
If only our mind stops sorting people according to such vague labels, we will find harmony. Until and unless such 'labels' are there, there won't be any peace among people.
