Do your ethics run your logic or does your logic run your ethics?

Does your logic run your ethics or do your ethics run your logic? Of example, would you logically deduct that if you steal or swindle someone you could end up in jail so you will refrain from doing such things, or if you cheat on your spouse you might get caught and then have a nasty breakup losing much of what you wanted to keep? Would ethics drive your logic like I would not steal from the boss (or company) because if I did and everyone else the company would close and I would be out of a job, if I cheated on the test to get the job/class/promotion I would logically deny someone more deserving that actually could have passed it the spot, or I won’t let my dog poop on my neighbor’s yard because he/she will have to clean it up to enjoy their yard plus it might start a trend where someone else’s dog might poop on my yard taking away my joy of using it until I cleaned it up?
