I do not out right disagree with hypocrisy being under your sins but believe it might need to be rethought.  With only three sins each one weighs very heavy, with this heave weight fear of being a hypocrite might inhibit a change of opinion.  Even though you would not be a true hypocrite when you change to a contrary opinion you could be one temporarily while you worked inconstancies in your new belief system.  I personally believe it is more important to constantly change your beliefs to compensate for their defeat when pitted against anther more logical set of beliefs than worrying about being a hypocrite.  However in general I think hypocrisy is bad to be incorporated in a set of beliefs that you have fully accepted.
   This is just an insight I think you might of missed however your reasoning for having it on may still be stronger than my reasoning against it.

I understand that, I think I misrepresented my point what I was trying to say was that when you change a major factor in your belief system it always takes at least a day or so of meditation to find the hypocrisies this has created and eliminate them.  Yet this state of having to eliminate the hypocrisies is desirable.  Also if that person talks to some one who knew his old set of beliefs they might thing him a hypocrite.  Its probably not that big a deal I just thought I’d mention it because some one like me may seem like a hypocrite in your forums as I change the way I view situations.
