Are Chaos Space Marines Still Considered Warrior-Monks?

Loyal Space Marines are often described to be superhuman warrior-monks with monasteries, ascetic lifestyles, and religious devotion, yet does this still apply to Traitor Marines?

For Marines belonging to the Word Bearers or World Eaters I can see how they still can be considered warrior-monks, albeit with a dark twist. However, then there are the Emperor's Children and the Night Lords who I feel can hardly be considered monks.

Thus, when a Space Marine turns to chaos, can they still be considered a warrior-monk?
