Well, I don't know about other people. Maybe if you claim to live by morals. But I certainly won't claim so. I don't make excuses and I don't try to determine good or bad on anybodys doings. I don't think that that is the way life works. No following your morals is ever worth not following your instinct. Say you really like a married man whom you want to get to know. Well it may be wrong, but it would be a greater regret to miss that opportunity for an experience in your life, than not following you moral values. Unless your only goal in life is following your own moral and values that you made a long time ago. things change and the world moves on, you can't stay still alone or you will only fall behind.
