Why would any woman want to be Christian?

[John V]

The father gets the bride-price whether he gives the daughter to the man or not:

Exodus 22
16 “If a man entices a virgin who is not betrothed, and lies with her, he shall surely pay the bride-price for her to be his wife. 17 If her father utterly refuses to give her to him, he shall pay money according to the bride-price of virgins.

So, money has been taken out of the father's decision, and he is free to decide whther the man is a creep or not.

Yes, the man is being punished for ruining a future sale, and has to pay a price (which, based on the various commandments, will vary, depending if she is a virgin, a widow (who may or may not be a virgin), a divorced woman, or the daughter of a Kohen.) The courts will decide and award the affected party (the father, not the girl), that money.

In this case it specifically says the price for a virgin.

Given that she is now ruined goods, the father can decide, not the girl, if it is in HIS best interest to give her over to the creep and get the full amount

It says he gets the full amount either way.
