Cheaters

Cheating is one of the biggest turn-offs for me. I always feel very angry and a bit of hatred towards cheaters. The problem is, I don't know how to deal with them. Here is my motto: if you cheats once and you know that you're wrong and promise to never to do it again, I let it go. But when you cheat again and again, knowing that it is wrong to cheat after I tell you numerous times that it is wrong and you still do it anyway, in a CONCEITED manner, then that's VERY unacceptable. At this point, I usually stay away from you as far as possible and don't want to talk to you at all. As a Christian, should I be like that? How should I act towards someone like that?

The person is a great friend of mine and I got to know him more over the years. He's a person that likes to cheat in school. In fact, he always encourages his friends to cheat cuz he says that it is a really easy thing to do. He has tempted me to cheat before but I refused cuz God hates cheaters. Anyway, my friend gets really happy and tells all his friends that he had cheated after writing a test. I tell him that it isn't right. But he says that everyone cheats in that class. He even teases me by saying, "the entire row of Koreans cheated for that test!". I got really angry and quickly asked him, "so did you end up doing well in that course?" he replied, "yup! I got an A-. Thank God I cheated on the first test! it was worth 40% too". Right there and then, I got sooo mad and just walked away. I wasn't particularly mad at my friend but I was just sooo mad at God for giving someone a good final grade when all he did was cheat and not put effort. I dont cheat, not even once, and I don't get an A- that easily without putting in a lot of effort. To be honest, when I heard that, I thought about cheating. But then right when I thought about it, I felt SO embarassed. SO naked. So sinful. I started to cry....

Anyway, after that, another friend talked to him about another test. Apparently, that friend came into the test room late so she had to sit with another friend side by side. She told us that their shoulders were even touching. That's how close they were so they were able to do the entire test together. My friend got really jealous and super mad cuz he didn't have a friend with him in his test room so he felt like he lost the opportunity to cheat.

There was also this time when we were talking about buying textbooks. My friend told me that there is no use in buying txtbooks cuz he said that he won't be using it anyway after the course. He told me that he's just gonna buy it, photocopy it and then refund the book. I immediately told him that it isn't a right thing to do but he didn't listen. He knows it is a bad thing to do but he keeps telling me that the textbook is worth 100 dollars and he doesn't want to "waste" money.

What should I do with this person? I just can't stand him anymore cuz he cheats over and over again even after telling him that it is wrong. He knows it is wrong but he still does it anyway. He lies, cheats, and manipulate others. Is it a wrong thing to do to stay away from him?
