Does evil exist? Certainly not an easy question to answer. I'm afraid though that the word "evil" has very little relevance to my understanding of the world. I see suffering and pain being experienced, and I see others inflicting suffering and pain. I don't call those who inflict suffering and pain (no matter how horrendous) "evil" though, nor in doing so am I trying to minimize or negate the very real horrors all sorts of beings experience (not just humans).
At the same time, because my understanding of the world is not dualistic (or primarily concerned with a
duel, whether that be between Good v Evil or God v Satan, etc) I see that even suffering and the pain that happens with living forces and energies coming into contact (remember suffering and pain are not just human-generated--there are unspeakable diseases and illnesses, there are natural disasters, etc) -- all have their place and value, much like Shawn was expressing.
I see things like this though because so far, I've come to the conclusion that there is a teleological (purpose or goal) end -- some kind of intelligence or inherent direction/nature -- to all of this. I have had to believe this myself due to personal wounds from past sexual, physical and emotional abuse though. By believing that there was a reason for that anguish I went through, I can see that without struggling with that pain and suffering, I would have never asked the questions I have, would never have become the person I am. The same could be said at a universal level ... without suffering and pain, the universe could never truly evolve .... or you could say, without suffering and pain, God could not fully know Himself.
All suffering and pain is transitory. It is an experience. Burn your finger and it hurts, but one day it will heal, if allowed (or if severe enough, you might lose your finger). That doesn't mean that we aren't left reeling with the after-effects, but how we handle that is up to us. Sh*t happens -- but what are you going to do about it? If you let the suffering fester inside you, I can guarantee that there will be even more damaging results than the initial experience. It's like letting a wound turn into gangrene and kill you ... all for want of some antiseptic. Getting things in perspective is kind of like antiseptic. It's how you survive and go on to live
well.
When you truly understand the nature of suffering, I think that is when you learn compassion and lovingkindness. These are not passive things, but should push one on to actually doing something. In a Buddhist sense, this would mean actively seeking Enlightenment, to be a bodhisattva. In the Christian sense, this would mean actively being Christ-like, modeling our life on his vajra/cutting truth that is also loving.
As for good/bad ... I remember one time getting more drunk than usual (and it takes a lot with me), so drunk that I actually behaved in ways that I later felt were degrading and irresponsible. I felt ashamed and guilty. Then a friend of mine pointed something out. Ok, so I messed up. Just get back on track then. ..... he likened it to meditation. You suddenly have a thought arise which distracts you, perhaps leads you off for quite a while on a bunny trail ... but you shouldn't judge yourself for this. This is the nature of mind. Simply return to meditating. So ... simply return to your center, to where-ever it is you feel you should be. Get over yourself and move on.
That's a very hard lesson to learn!
Ultimately, I think the real question we should be asking is not just why do we suffer (as opposed to experiencing pain .. suffering more in the sense of clinging to our experience of pain and reliving it over and over again) ... but also
why do we perpetuate suffering in other beings?
Is that because we are sinners or because we fell from Eden and inherit original sin?
Or is it ignorance? If we TRULY understood what we were doing to others, would we inflict it on others? And if we *did* understand that, fully (as I think there are probably some out there who do) and still inflicted pain onto others, then does this derive from our own suffering and pain and our inability to express that anguish any other way? I truly cannot believe that anything or anyone is "evil" but more like someone who is very sick or blind (in more ways than one) and they need our prayers, blessings and compassion more than anything else. I can also see where the Buddha was coming from about seeking to bring enlightenment to all beings.
This does not mean letting them in the meantime have freedom to wreak havoc. It *does* mean cutting through all their crap, their barriers, anger, sado-masochism, hate, ignorance, greed, vice, etc ... and touching with the pointed sword of truth their heart. Locking these kinds of people up in prison doesn't actually do this ... it simply puts off our responsibility to try and help this person until another time, another life, any time but now. Instead, we need to acknowledge that just as we have problems in ourselves, so we do in our society and race, and this cannot be blamed on any disembodied or idealized understanding of "Evil" or "sin". I whole-heartedly disagree with this, and find such concepts degrading to any sense of God or His Creation (or the Universe, or whatever you want to call it all).
These are just snippets of many different thoughts and responses I have to the original question. This sort of topic always challenges my present conceptions and leaves me grasping for a more satisfying understanding. If I understood it perfectly, well, I'd be enlightened wouldn't I?
