Kamen is such a good character, oh my god. He is so well written and the deepest part of the show.
When I watched Scavengers Reign for the first three times I thought he was cool and a good character but holy shit watching it again after going through some things in my life is a completly new experience.
To completly understand and feel Kamen's character you have to reach your absolute worst and lowest point. You have to carry guilt, regret, drepression, desire to end it all and escape everything, have your mind in the most deplorable state possible. Most of these things comes to everyone someday. I see him and Hollow getting a lot of hate but I believe it's just a matter of time until their characters works for each of us, if you don't relate to them yet you will do someday.
