I don't know what to make of last night's episode of ER. But as a character revealing piece, it highlighted many of the character's levels of comfort when it came to ethics and morality. Weaver didn't seem to have any problem not following the rules for politicos. Susan is as straight an arrow can be. Romano can kiss ass with the best of them. Luka probably is haunted by his compassion, which seems to be at odds with the level of care tolerated in the ER. Carter seems comfortable making micro-level contributions to impact the world (his career as an ER doc, his visit to Ed Asner's character's clinic), while having the means (as Abby pointed out) to make macro-level improvements to the quality of life in his community with his ties to wealth. Pratt's "brother" Leon is going to cause him more and more heartache with his lack of street smarts, and day he'll have to make some more painful decisions about how to take care of Leon.
