Charles logan :

Season 4 climbed his way into the Presidency due to untimely death of other President, plane got shot down. Then had his own indirect order to remove Bauer for good foiled buy a warning buy David Palmer .

Season 5 , all these people die due to him being again indirectly involved to killing of Palmer and Michelle and almost get Tony, He thought he was done his legacy made with peace agreement with the Russians , Then his wife went off the deep end figuring out his evil plans and he had killed palmer . Bauer makes his way onto his private Helicopter gets kidnapped threatened to be killed thinks he escapes but pen planted buy Jack and Martha getting him admit he is carted off .

Season 6 ,he stabbed in the neck buy Martha we are left hanging nor knowing if he lived or died .

Shows up in S-8 again trying to rebuild his legacy ,in the end kidnapped and threatened buy Jack twice in the end his legacy rebuilding is over as his attempts suicide .... He had a few real bad days ...
