In this example I think it is very clear because robbing a bank isn't an issue of personal morals to me, it's a criminal act and it's clearly wrong. As a T I would have to advise against this, or anything illegal or that I thought would be detrimental to the clients well being.

I think an issue like abortion should also be clear cut as well. People who are against it for religious reasons don't need to be talked out of their belief, I think that should be respected even if the T is not religious and doesn't see an issue with abortion. conversely if the T is anti abortion for religious reasons and their client is going to get an abortion, I don't think the T should talk them out of it because of their own personal morals. I think this is where it might get really difficult.

For me, if I was getting abortions and I knew my T was morally opposed, I would have to go see a new T because I'd know that one would despise me. That's just me personally.

I personally think it's important to share a lot or most moral stands with your T, just seems to make things easier. As a non-religious person it was important to me that my T was also non-religious. As a non-religious person with high morals it was important for me to find a T that was similar, and I've tested mine to make sure he indeed is a good man.

It seems like the problem would be worse if the T had more morals than you, and a bit easier if they had less. If they have more morals then they might come to dislike you or be disgusted by your acts. But on the flip side, if you are anti-abortion and the T isn't, I don't think a T could dislike you for not getting an abortion you know what I mean. I'm not sure what you guys disagree on, but it sounds like you have more morals than your T. My guess is your T is trying to help you unburden guilt because you're human and everyone makes mistakes, but that's just a guess. If they are trying to talk you into doing stuff that is against your beliefs though, that is a no no in my mind and you should tell them that!
