Many "men of sin" have sat in the Chair of Peter, including Peter who denied Christ 3 times and later as Pope had to be rebuked by Paul.
I am guessing you misunderstood what St. Paul meant with the 'man of perdition'. If you read the verse in context you will note that he was speaking of the anti-christ. Thus your post gives implications that you were calling Saint Peter the anti-christ.
You obviously did not mean it that way but you should know that it is outrageous to apply that verse from Ephesians to St. Peter.
