That boy is always brooding in the manga, seriously... You get treated to a few flashbacks, and he constantly refers to THE DEATH.

In volume four, when the Alma Kinan archers turn up to help Hugo & co in the vs Harmonia battle, he learns the hard way about war/principle, and compares his killing the Harmonian soldiers with Chris killing . I'm not sure if he does this in game or not. And then he cries some more. TT__TT Hugo-angst breaks me really.

and HOLY SHIT Suikoden 4 is getting a PAL release. Dude!!!
