I can never remember poor "Kuwagata"'s name, but he is indeed "my boy", totally my favourite of the male characters in the series and a righteous dude to boot.
Turning him from a generic monster rapist with a weird squeaky voice into a fairly amicable kindly uncle type with an ear for others' troubles and a shoulder to cry on was a brilliant idea. Partly as it's so strange to see, but also because I like things that are unexpected, and I have to say his death was actually fairly poignant, due to the futility of his actions and the really inopportune timing of the young girl's arrival.
And I must admit that so far as vices go, raping Anri is one that I think I can understand.
Also, who honestly gives a fuck about Dyna?
