Interesting read Terry, thanks for sharing,
For me, your story reminds me of how selfish we are as humans. I'm not saying it's always a bad thing, maybe we need to be selfish just to survive sometimes.
When it comes to things like sex, drugs, drink, gambling etc, those are the things that literally hurt others around us including as yet, unborn kids. I was raised by a man that wasn't my biological father simply because of a one night stand. He left, mum got married, life goes on, but that single act affects a lot of people. Sure, sex is great, but what happens if a pregnancy occurs? Do women that get an abortion, or adopt out their kids really ever get over it? And sadly, that's such a common occurrence. The kids pay for the sins of their parents.
So much misery can be attributed to the selfishness of individual humans. But, life goes on.
