How on earth is that justice for the darkeyes Amaram killed? Plus if Dalinar has a problem with how Sadeas used the bridgemen, do you think he'll be fine with what Amaram did? Note that this was previous to some of Dalinar's development and his belief in the codes has risen considerably.
As far as Amaram goes, if I had to guess I'd say he used to be someone decent but is being corrupted by Restares. On the other hand considering who Dalinar was previous to the series, Amaram being an old friend of his isn't really a glowing recommendation, although it's not a bad thing either.
