Coinnosseurs of the deadly sins divide them into the warm-hearted or cold-blooded sins. Lust, anger, and gluttony in this reckoning are thought warm hearted, bodily sins, proceeding as they do from the physical passions; pride, greed, sloth, and envy are cold-blooded, proceeding as they do from states of mind. The cold-blooded sins are more rebukable, less forgivable, and (with the exception of sloth) inherently crueler. Envy, a case could easily enough be made, may be the cruelist of all.
