TIFU by googling my sister's fiancé II

So for those who read my previous post please visit here.

Update 6: I met my sister for lunch yesterday and basically told her what was going on and how I found out about her fiance. As my feelings were she knew came into fruition. she told me that she knew and that he was set-up by his ex-wife. No surprise there, the guy practically blames everyone but himself. It's no surprise that he would tell my sister that he was set-up and that could very well have happened. Now the part that surprised me is that she wants to break-up with him. She has only lived with him since June of this year (a little over 2 months). And get this; she doesn't want to break-up with him because of his past/history. She wants to do it because of his complete laziness and slob of a lifestyle. She feels that she'll have to be the bread winner and he is not healthy and is in his early 60's. Exactly what I told her before that he's only with you for your insurance, once you marry him and he gets older, you're going to have to take care of him. 2 months in and now she sees that this is what's waiting for her if she decides to marry him. She cried, she wasn't upset at me, she wasn't defensive and she was genuinely sincere about my opinion of the situation and my feelings toward it. I told her she's welcome in my home anytime but he isn't. This seems like a victory and it partially is. I did what I set out to do with very minimal blowback. The next phase is my sister NEEDS to part ways with this guy and do it sooner rather than later. This is the hard part as anyone who has ever broke up with someone they lived with can tell you, this next step is the hardest. and it's a step she's going to do by herself. I'll update if she does but I just wanted to let everyone know what happened and hopefully she does the right thing for herself. I left her with this; sometimes it better to be by yourself, than marry someone who's going to make you miserable.

TL;DR: Googled my sister's fiancé, found out he was a sex offender, I met with and told her, says she wants to break up with him.

I want to thank everyone for their concern and help in this matter. All your comments were welcomed, even the guy who called me a pussy (I actually needed that cause I was acting like it).
