How does one know if they are not inherently evil?
In my personal opinion, there is no good or evil. These are terms that humans use to judge how they see each other on a societal scale.
What is evil today may be good tomorrow.
What is good today may be evil tomorrow.
Personally, my answer? Staying true to yourself and carving your own path is what is most important.
Do not stress about what other people believe to be a standard. Remember that the person who is most familiar with you - is yourself.
I hope all is well with you. It's good to see you on here and reaching out.
