....IMHO, it is not so much that the drugs,(yes alcohol is a drug)covers the person's conscience but that it allows suppressed evils to manifest.
Total agreement. As I mentioned up the thread, taking hard drugs or alcohol will NOT turn you or me into a murderer. I might do something stupid but certainly not evil.
Intoxication can indeed break down one's resistence to the evil that's already inside. But one decides to take the drug/alcohol. And obviously the terrorists in Beslan were commited to evil, drugs or no drugs.
