You thought after you'd known someone for many many years but in the end you don't. What you saw was surface level. Then the lyrics "you know what is what, but you don't know what is what, what the fuck!" ring true and repeats itself constantly in my head.

We are all human. We alone and none other may decide for ourselves the path that we take. I doubt that a person's innate nature should be to blame for being so, but rather one's ability for self-reflection. Only when they've achieved that state of consciousness, perhaps one could mark out personal flaws and try to make a difference. Everyone makes a decision to change or not.

That is only IF, they knew there was something to change.
