I find Tamlin's fate exaggeratedly cruel

I'm reading silver flames and I think Tamlin's fate is too cruel. Yes, he was an asshole and made mistakes, however, I see him more as a fool who acted out of fear and desperation than a bastard who deserves hell.

I don't like the way he is treated, especially by Cassian. Obviously he caused a deep scar on Feyre, but I see his fate as disproportionate.

I don't know what fate awaits him, but I admit that I feel sorry to see him wasting away alone in spring.
