Derech HaMelech, your thing with bechira does not sound right at all!!
Ado…, are people who are or have been married not innocent? The way somebody taught you to understand innocence, is Christian, not Jewish. They think, it is better not to get married at all, for example. If a person is aware of certain ta’avos or even has them does not make that person bad. Again, one is not allowed to read/look at inappropriate material, though.
