Opinions

If we assume for a moment that something called the right opinion exists, then does it also matter why we have that opinion? Is doing the right thing for the wrong reasons acceptable
What brings on this issue is a book im reading about the Srila Prabhu somethings views and opinions and included among them are whether we should be meat eating or not, abortion is right or not. Now the end result is the same, Im a vegetarian by choice and i dislike the practice of abortion(except certain cases like rape,or the mother's life being endangered). The srila whatisname has the same end opinions but the reason he has these opinions are very different from mine. It irks me to think that if it came to a debate , said specimen would be on my side.
But is he a lesser evil than perhaps those who would disagree? I think not.
