The whole idea of a global character trait feels deontic and binary. Virtues are ex post descriptions of actions taken, not guides for conduct. For example, I don't believe the charitable person thinks "What does charity demand?" Rather, that person thinks "How can I help?" and thereby instantiates the virtue of charity. After a while, a person develops a history of assessable decisions, and we reify that history as "character." Whether there is "no such thing" as character is thus a semantic question of what it means to be a "thing."
