Karthus' tenure in the League of Legends is one of the more unusual ones in the history of the League. First, it is highly unusual that a lich who was known for isolation and hatred of life would even be a willing part of an organization which promoted the preservation of life. Next, Karthus specifically eschews the accrual of power and influence gained through service to the League; he is essentially an unpaid volunteer. This behavior is completely different than what his life outside of the League would have onlookers believe. Karthus has never spoken about his intentions in being a champion of the League, and in fact becomes quite agitated when asked about it. In the interests of not aggravating a lich, most sensible people subsequently drop the issue.
