>>8 you're very much on the dot. Emotions are to some extent flaws, but not all emotions equally. If you go deep enough, you'll see that they exist for the purpose of justice. It's a flaw that keeps us alive and others. It creates a society we can live in, or stay alive in.
If emotions didn't exist, taking care of someone, particularly a baby would be difficult. It's that motherly instinct, sympathy. A lot more common in females than males. It's the reason why most butchers are men and the dominant one in raising a child is generally the mother, being void of some emotions or having a lot of it.
And to put it simply, the possible reason for my drastic change would be that I've almost 'completed' the knowledge needed in this area. If I am angry it's too simple to deduce why and get myself back on the ground, or not be like that from the beginning. But even if someone is void of emotion, existence still has a purpose.
Yes I'm basically jumping off to the other side of the fence right now. It's a train of thought I can't stop anymore, but it'll stop somehow just not yet. When I was a younger people would tell me to stop thinking like this and I knew it was for the best. But people are genetically programmed to want to learn, some much more than others. It's dangerous to yearn for open-mindedness. You're right no matter how knowledgeable I become I'll always remember that ignorance is bliss in some cases.
But the best I can do to ease this amount of knowledge is teach it to someone else, if they're willing to learn...it could continue the cycle though.
You didn't cheer me up but thanks for the luck. More insight however!
