We definitely did. Asher in 2B was all about his guilt. He was drinking (most prominently in 2x10), he offered to turn himself in multiple times (twice in 2x12, once in 2x14) and he apologized to everyone with this speech (2x14):
"Excuse me, everyone, if I could have your attention. I would like to offer all of you an apology. [...] Uh, I'm sorry for ruining your lives. Uh, yeah I don't know. Maybe none of this would've happened if you all hadn't killed Sam, or if whoever hadn't killed Lila [...] Anyway, the point is, I messed up and made you all stick your necks out on the line for me, and I just want to say thank you. Thank you for protecting me after I, you know - killed" [Connor interrupts]
I'm by no means an Asher fan, his antics are like nails on a chalkboard to me, but to say he never showed guilt is completely untrue.
