Go for it man.

If you truly feel you are a good guy, your friend will want his sister to be with someone like you. If you're friendship is actually solid, dating his sister won't be able to ruin that.

BUT if you are at a stage in your life where you aren't looking for something serious then stay the fuck away. If you are in that boat, become friends with her and get her to hook you up with other women.

I'm going to assume you are young and haven't had to experience this yet. Most of my friends when I was in my teenage years to my early twenties are no longer relevant in my life. Not that they aren't friends but I only see maybe 2% of the people I hung out with lots in my early twenties on a semi-regular basis. People get older and they drift apart because of jobs, family, life in general. There is a chance in 5 years you may not even see this friend of yours more than twice a year. There is a chance this woman could be someone you marry. Worth a shot in my opinion.

I've gone with a few friends sisters and it hasn't ruined a single friendship. Only reason is because I'm a pretty respectable guy for the most part and don't treat them like dog shit. I'm still friends with each ex and their siblings.
