Fact of life.

Once conceived and then born and then raised through childhood unless someone or some event kills us during those phases of conception, birth and being raised what choice do we have.

Now once raised I looked around at life and what it had to offer me, and I chose the path that would get me to where and how I wanted my life to be. Where I could live my happiest type of life for me to enjoy despite all the horrors and tragedies on my path and to share love with my friends and loved ones. To be able to extend a helping hand to a person in need and that truly wanted to
improve their life as I have done for myself.

This is my best tangible answer to your question barring all the influences you asked us to bar.
