Ehhh...yes and no. I won't pretend to be the foremost theorycrafter on the subject of Sha, but I'm sure negative emotions extend further than you're allowing here.
Sure, there's a Sha of Anger and a Sha of Fear but I'm sure there are lesser sha akin to regret, sadness, loneliness, and maybe even (in the case of that little brat Anduin) the sha-of-my-daddy-is-a-warmonger-and-im-pretty-torn-up-about-that.
