Is this one step away from "not giving a shit"?
 

If I look back 3-5 years, I cared about people, and was a good friend that listened and cared about what happened to my loved ones. People trusted me with their life and money

Now people still trust me, and I listen, show affections and help - BUT not because I really care, but because my brains is telling me its the right thing to do - the morally correct way to act. Done out of respect of another human being, not because I really care about them with my heart - only my brain.

I think the only ones I love with my heart, is my Mother, brothers and my two dogs

.... does this make me a asshole? I'm not hurting anyone, and I would never ever cheat anyone. But I'm getting really close to not giving a shit and only do what I do, based on the respect I have for the individual and the actions of those people

Nope it doesn't make you an asshole. It makes you selective. I don't trust alot of people either

nah, have to take care of number one, yourself...good friends are hard to find.

It is actually a smart move. so many people in todays day and age are only out to fuck others.

I like the whole do unto others way of living.

that is also part of the reason it's "the right thing to do" .. but it just sounds a little cold if I come straight out and say "I'm only being nice to other people, so they are nice to me as well"

Having respect for others is a good thing so no it doesn't make you an asshole.

No, it doesn't make you an asshole. It makes you quite honest and normal, actually. Unless your purpose for writing this was to make people think that you are honest and normal when really you are not, in which case you are dishonest and normal.

I think I might just have been a blue-eyed Idealist in my younger days then ...
