Caracala's Purge of the House

The stories about caracala's behaviour in rome at this time aren't very positive. One of the vestal virgins he's alleged to have hraped, and he put her to death,. as well as three others. The romans may believe there was retribution meted out on caracala because later on in his life he became impotent. A u say, this is as far opposite as you can take it. This is a temper tantrum, really.
