@Leadfoot,
There was a saying in the Temple of Delfos. used many times by Aristoteles, and it says "Nosce te Ipsum;" which means "Know thyself." I'm not saying that Religion is bad or anything; don't get me wrong. I believe it's a wonderful placebo for people that don't have the courage to take responsibility of living life and its consequences. I know, its overwhelming; I've been there; also I believe it's a wonderful placebo for those afflicted by personal problems, and are unable to see the light at the end of the tunnel. But is just a placebo.
To answer your question. Yes, I've always question myself, "Why human beings are mean to each other?," "Why there's so much violence, rape, murder, theft, treachery, and so on among human beings?" believe it or not; I was once an Apostolic Roman Catholic. Both of my parents use to give spiritual retreats sponsored by a catholic movement and their parish priest, but they were miserable in their personal life. domestic violence, glasses, dishes, pans, flying back and forth. The same thing with their friends, and churchgoer people that I knew back then; I asked to myself "Why are they arguing and bickering if they're suppose to be converted and stronger? Several times I said to myself "I'm trying to be a good catholic, but is so hard with so many temptations" and prayed to be forgiven for my weaknesses and mistakes, but still, I couldn't avoid to keep repeating the same mistakes. I was unhappy. Then I started to realize that I knew that I was weak, and I was asking God for help, and he wasn't answering, and I wasn't happy. Then it dawn on me that I didn't knew myself. You may say "that's ridiculous," and I was hoping God to solve my problems for me.
So I dedicated myself to try to know who I am, and started to dissect my actions and reactions. People's actions and reactions. After dissecting and studying those factors I've finally got to the conclusion, and I'm going to put it in math therms to make it simple : survival instinct + emotions = ego. and ego + survival instinct = ego-centrism. What do I mean by " ego + survival instinct = ego centrism?'"I mean that our survival instinct are so amplified by our emotions that they give birth to ego-centrism. Which is the compulsive need to control things, situations and people around us in order to feel safe. That's the reason why we're liars, manipulative, and mean to each other. I'm not saying that is bad to have ego, but 99,9% of the people doesn't understand that those are the poles of the personality therefore are unable to balance it. And is not something easy to do, I'm far from it, but at least I can discern, and be aware when my weakness is going to betray me, and avoid to incur in that mistake.
People often confuses Maturity with experience, or age; that's a silly thought. Maturity is the act of giving up something that possibly could make you happy for someone's happiness, for instance: when you keep your mouth shut to make your wife happy, to make your children happy, to make your parents happy, and so on. I'm glad that you found your answers in your God, and you feel that that's enough, but I don't have the patience to punishing myself for not conforming to a (which I consider nonexistent) God's unrealistic standards and feeling bad about myself, and make everybody around me, miserable, and be an hypocrite outside of my house, and an SOAB (pardon my french) inside of my house. I'm happy to know my weaknesses and strengths, and happy to know that I'm strong enough to at least recognize my weaknesses, and try (and most of the time now successfully) to overcome them. And not settle, hopelessly for an nonexistent God to help me overcome them.
