They don't.
This was a trait unique to Count Dracula, and as he was such a famous vampire the stereotype has been applied to all vampires. Dracula was a champion of the Christian knights of Transylvania against the Muslim Turks, so when he became a vampire you can see how his new life-style would conflict with his deeply ingrained christian beliefs.
Vampire do not have the ability to effect emotional growth. The person that they were when they died is pretty much who they will be through-out their existence. So what ever quirks they had as a person will remain with them as a vampire. Dracula had many of these. He couldn't enter a building unless invited, couldn't cross moving water under his own volition, couldn't stand the sight of religious icons.
