Does the Bible (Revelations in particular) have a propensity to cause and exacerbate mental illness?

For those who are predisposed to mental illness?

Like the Revelations, 666, anti-christ, second coming, Armageddon, etc.

Do you believe this stuff can make people mad?
Update: What's the big deal about the s. It's not like that is important. I have actually read that book of the bible many times.
