As far as the Christian ethics are concerned, I do not think this philosophy is espoused anywhere in the texts. You aren’t supposed to be nice to people because they will be nice to you in return. You are supposed to be kind because it is what your god asks of you. Your reward supposedly awaits you in heaven. There is no promise of earthly rewards. There is no promise that living a virtuous life will be easy, painless, happy, rewarding, or positive at all.
There is a great line in the movie ‘21 Grams’:
Your religion is not there to provide you with a happy life. If you get screwed (walked all over, out $20, waiting in the car lane) following your beliefs, well then, tough titties. The Bible never promises that it will be easy or fun to be virtuous in this world. To expect as much is not very Christian, IMO. You are supposed to take all of the pain and suffering that comes your way and deal with it all in a virtuous manner, trusting in “God’s Plan” when you get screwed. As far as your religion goes, the answer to your question seems pretty clearly laid out to me.
Personally, I’m an agnostic, so I am free from a belief in an afterlife, or a god of any kind. Without religion, it is up to me to develop my own moral code. To me, there is nothing that is objectively wrong. There is no obvious meaning or morality. There is only the meaning which we give things. In a cold, uncaring universe, or in a simulation, there is not much reason to do anything unless it pleases you to do so.
I happen to find comfort in being nice to people, I love humanity, and I want peace and happiness for all. Still, I don’t really obey laws - government’s or religion’s - unless it conflicts with my own personal moral code. Government’s have their own agendas which are seldom, these days, based in good intentions. Rather they are about maintining power structures and control. For me, that means vices galore: Booze, Gambling, Women, Some-Things-We-Won’t mention, and, if I feel it benefits me, I may lie or cheat. Fuck them, their laws, and their repressive moves. If I want to do something, I’m going to do it. And if it is illegal, or ‘immoral’, then I will do my best to not get caught.
I am not, however, without a moral code. My philosophy is that I will try to make every moment of my life feel as good as it possibly can. I’ve found that if I treat good people poorly, I spend time feeling bad. Cost benefit analysis then leads me to be cool to people, so that I will spend less time feeling bad. I do it because of how it makes me feel, not because of any self-proclaimed authorities telling me what is ‘right’. What makes me feel good is treating my friends well. Honesty, respect, and kindness amongst people I trust makes me feel really good. I’ve found that many, many, people are not worthy, unfortunately. So I treat jerks like jerks and good people like good people. I tell the truth to my friends, and lie to my enemies. I don’t follow anyone’s code but my own, and generally, I am one happy MoFo.
If you fear your god, then suck-it-up and take the pain in expectation of a reward. If you suspect that this is the only existence you will ever get (ie no afterlife), then I suggest you do everything you can to make it as pleasant as possible for yourself, whatever that may be. If it means vice, then go for it baby. If it means virtue, then knock yourself out.
I would also like to point out that looking out for #1 doesn’t have to mean screwing everybody else. Being kind, networking, doing favors, altruism, and similar things can make me feel good. So I help people (for example - I walked a blind man up 3 stories to catch a train the other day, missing my train as a result), I extend my social network, I try to ‘be the change I want to see in the world’. I do all of these things for myself (#1 as it were) because they make me feel good (in the long run if not immediately), and yet they still result in other people being helped or recieving kindness. Those things make me feel good and that is why I do them, not because of a belief in some ultimate judgement or objective morality.
To sum up: I’ll take an order of vice sprinkled with honest friendship, a side of random kindness, and a tall glass of screw anyone that get’s in my way (in any endeavor I may engage in - nice or naughty)!
