I do believe people have inherent value even if it's been twisted by life experiences. I do think most people at one point in their life have an element of good in them. Even a psychopath. Even before this, as a child this evil person was probably as innocent as possible given life circumstances. Like StopDog said, worth is often relative. People who are evil by most standards can have another side to them where they do feel real love for famy members or others and would never harm them. Their family might be unable to believe such evil can reside in this same person. In this part of their world, they may have a very clear value. Even a serial killer who meets with a psychiatrist to gain insight into their own behavior has some worth as a human if only because we might learn from him. I think people are so complex and there are many ways we can derive value.

When normal people doubt their own worth, as I have, I think its often due to where they believe worth is derived from. Do some women base their worth on societies standards of beauty which are so hard to live up to (especially as we age). Does a teen base their worth on how many "likes" a selfie on social media receives, and how fast they receive it? Absolutely. It'y the same for men...so many feel worthless because they haven't achieved the things that are expected of them. I think a lot of us hyper focus on perceived flaws and can only see ourselves in a one dimensional light. We can over identify with our psychiatric "issues" and define ourselves and our worth by them. I think therapy can be a great help with this. A t can help us identify other positive aspect to our selves thad we never knew existed.
