and how do people get twisted?
a spiritual influence (satan and his crew) that happens to them or they choose the first time, and then it is repeatedly chosen.
satan needs just one time with some people and hooks them for life.
Just as an evil person can choose doing right one time and break thru the spiritual hold and start choosing good more than evil, thanks be to God!
I suppose you could call pornography, being invited to join in debauchery, reading or hearing about sexual things in the news media or conversations with other people spiritual influences.
Those things are generally the pregenitors.
