People often do not know how they will react in certain situations until faced with them, regardless of what they say they would do.
They also often have no idea of all the negative consequences that might be explained them when it actually came time that they were in a position to do something.
Pursuing a civil instead of a criminal case is not in the least suspicious that this person is making a cash grab.
Imagine a lawyer is hired by you and tells you you will not win this case, or even you will win this case. But your life will be ruined. In the name of defending himself in court, this multimillionaire’s team of lawyers will destroy you. They will traumatise you. They will contact your exes, your family, people you went to school with who you want to have nothing to do with and they will ask them about your behaviour, your reputation, any smidgen of information that may claim you might not be the Virgin Mary and use it against you as evidence. When the severe trauma of the court case comes to a close your trauma will not be over. People you had thought would you would never have any contact with again will have been asked to give evidence against your personality.
As a result of you being attacked. Do you want your life destroyed? Do you want victim to be your main identity that you take forward due to the stress of the case and revictimisation by men paid to make you look like you were asking for it, a liar, are trying to use and manipulate someone that you actually want nothing to do with ever in your life?
Do you want the memories of this trial and being forced to go over things again and again in painstaking detail, have the kind of intrusion on your life you would only otherwise need if you were going for a job working on top secret government secrets, to overshadow how you feel for the rest of your life? To give you no chance to potentially slowly let memory fade more and more to have some hope of moving on and having the rest of your life as your own.
A civil case carries a much lower burden of proof than a criminal case, maybe it involved less raking over the coals of the alleged victim’s life.
If the lawyer says look they’ve offered you a deal or they’ve said they’ll destroy you - you can tell me you’d take the route of going to a criminal case, but I wouldn’t believe you because I don’t think you’d know yourself no matter how stridently you claimed to.
