I think Kaladin will need to let go of his hatred towards Amaram, as part of his growth as a leader. I think his hatred is partly a selfdefence mechanism, something that overshadows his guilt at leading his squad to their deaths. The guilt was too much to deal with for Kaladin, so he buried it in hatred for Amaram, and lighteyes in general. Understandable, but not very constructive (or honorable).
Kaladin the Racist must die, so that Kaladin the Radiant can live. He must learn not to let grief, hatred, or guilt, distract him from doing his job.
Amaram will be the one that "teaches" Kaladin this lesson, I think. I can't wait to see how it will happen (or not, if I'm wrong)
This is why I don't have any negative feelings towards Amaram. I certainly don't think of him as a bad person. IMHO we haven't seen any bad people yet. Not even Sadeas is bad. Dalinar explains his actions to Elkohar as; "A very Alethi thing to do". I look forward to the bad guys showing up..
