I tell people this over and over again: don't attach your faith to people. People will come and go. People will disappoint you. People will divulge dark secrets. People will turn out to be the opposite of what you thought. Allah is perfect. His Messenger (peace be upon him) is a perfect example, and the religion is a perfect methodology. Attach yourself to the principles instead of the people. That way no Shaykh going wild or role model going rogue will be able to shake your faith.
