First of all, retarded people, we won't be talking about them. I'm curious about intelligent, consious people. What does make them 'bad'? Having bad thoughts? Realising them? Doing bad things with good intentions? Doing good things with bad intentions?
I doubt whether it's possible to be bad. Everything is fundamentally necessary. That doesn't mean that I condone violence or anything of that sort...but just that existence is as it is. Every single atom that exploded out of the big bang is all we are. We can't be any more or less. Take a piece of it away, there's no reason to believe the whole would exist. Technically speaking, all the bad things are very good for you.
I think that the measure of bad that one is willing to express is directly proportional to the measure of disconnect they feel from the rest of the body of humans.
Not objective but I tend to think you should aim to do the right thing; The Buddhist 'right thought', 'right action' etc framework is useful here. It then gets more fractal and complex what 'right' means.
Having bad thoughts and not act upon them because you think they are bad obviously makes that individual a better person. No one is solely good or bad, it's better to make such judgements about their actions and motivations if known, not to project their bad motivation or action on the totality of their being.
I'd say there's no such thing as a "bad" person. A person can just make bad decisions, which is relative anyways.
Being high maintenance. In other words, they burden those around them with matters that are their own to be responsible. Or lack of competency....they aren't very good at those matters that are theirs to do well, and ultimately burden others.
Interesting question ... the short answer is Fear. Fear causes extreme behaviours. when the fear is experienced at a young age the experience is likely to remain as a template for future behaviours. (See "the brain that changes itself" fairly recent publication.) "Fear of Freedom" by Erich Fromm spells out individual subjective processes in detail. and never forget the I Ching's truth that "Earth nourishes ALL men, be they good or evil". cheers!
nothing makes anyone bad, because there is no such thing as being bad, or good. there is only doing good and bad things. and no matter how hard we might try not to, we all do at least some of each. what matters is how much of which and how much we prefer of which. and of course the extremes of harmful, one either seeks to avoid or one doesn't.
What is a good thing? What is a bad thing? And, how can of course, the extremes be harmful if there is no such thing as good or bad being? There is no accounting for taste.
Truly bad people, the serial killer types, simply lack empathy. In fact, religious people also lack empathy, because they rely upon a mythological being for a reason to be good.
I tried to rep you for this because of course we find those most agreeable whom we agree with. Our protections extend naturally to that which we identify as our own.
