What if you are a child rapist but are ok if you let Jesus into your heart in the end?

My whole point was, in my zealous friends' eyes, a serial killer who has repented can be saved, but if I spend my life working with orphan children and don't let Jesus into my heart, my soul is damned. If Christians can believe non-Christians can be saved without belief, then why proselytize? Regardless, because of my lack of belief in Jesus--which is literally what Christianity is about--I don't think I could ever become Christian. Unitarian perhaps, but are they really Christian?

Where I currently live, I don't want to attend bible studies--hopefully you can understand by the descriptions I've given of the zealouts who live here (read: the holocaust happened because Jews killed Jesus--ISIS is doing some good because the museums they're destroying contain false idols; the fact that Joe has new, non-Christian friends is because he let Satan in his heart--everything they say is a walking contradiction) I don't know if "mass" is the right term--whatever it means to go to church. This is a small country, and the people here are very intensely religious. Maybe if or when I go back home I'll give Christianity another go, but I was more interested in exploring Judaism.

Sorry, I know my post was pretty inflammatory, but I hope you can understand based on what I'm having to endure here. I have lots of culturally Christian friends back home who have never attempted to convert or condemn me--I mean some of them have said that gays don't belong on this earth yadda yadda, but nothing as intense as what I've experienced here. I'm just saying that--regardless of the shapes and sizes believers come in--the core beliefs contradict with the opinions I steadfastly hold. So I was curious about Judaism.
