Input: My girlfriend "Amy" lives with a girl she knows ("Kate") family. The family is nice enough, but their daughter Kate is horrendous, she and Amy used to be friends, but lots of things that have happened between them, has caused a rift (it is not worth going into detail). 

Amy just told me that Kate is a kleptomaniac, and she has stolen at least $2000+ worth of clothes, books, games, toys, and makeup. We live in a fairly small town, and we know people who work at the stores she has stolen from, and Kate would (without my girlfriends knowledge) use her a distraction letting her talk to her friends for minutes while she would go and shoplift. She will also go and scout out stores for security cameras and guards. What I'm saying is this girl is not just doing it in the spur of the moment, she is purposely making plans and using people as distractions so she can do it. She has admitted that it gives a rush.

I am disgusted by what she is doing, but not only cause she is stealing from people we know and are friends with, but she is also using my girlfriend to do it, Amy only just found out the other night about what has been going on for months. She is not poor or by any means struggling, she has a full time job and lives with her parents rent, food, and gas money free. So she does it for the thrill, which I don't even know what to think.

Would I be the asshole if I reported Kate to the police or stores she has stolen from?
