I Can't Help Anybody Who Doesn't Want To Be Helped

I'm so sick and tired of helping someone or somebody when they give you a lecture of why they didn't need it. Every time when I do something courteous of trying to be helpful, it always comes bouncing back and it gets interpreted wrong. From now on, I am no longer going to help anyone, unless if they ask for it. I don't appreciate being treated like shit and make me the bad guy just because I want to do something helpful for someone. I don't understand why people get so offended by it. It just doesn't makes sense to me whatsoever and they can deal with there own crap that I don't want anything to do with.
