he has a point when he is talkin to Mustang and Riza. why put on the uniform and go to war if you arent ready to kill, that is just stupid. of course that is just his intelligence seeking an intelligent excuse to enjoy killing

Mustang. Hawkeye. Hughes. Armstrong. --- Good, admirable people. They wanted to defend the people of their country -- unaware of the rot that lay at its very heart and would drag them down into its bloody filth.
But they soon discovered they weren't sent to defend Amestris. They were sent to exterminate the Ishvalan people like blighted cattle -- down to the last bleating calf. This episode really makes you feel the pain of good people who are forced into a hell like this by their own noble choice to serve their country.
As much as I loathe Kimblee, he at least makes one valid point--- which Hawkeye seems to have taken to heart. The naivete of the eager young soldier is swiftly crushed by the brutal truth of the battlefield. Doesn't make Kimblee any less of a blood-thirsty monster. It's one thing to defend ones' country on the battlefield against an enemy that actually threatens harm. It's another to continue fighting just to survive yourself. It is another all together to ruthlessly slaughter an entire people --- and enjoy it.
Mustang and co. understand that and carry the burden of knowing what they did. However, rather than letting the events of Ishval turn them into cold hardened killers or weigh them down into guilt-stricken inaction, they chose to fight a new battle. This time it was to reclaim they country they love and make it a place where such atrocities are seen for what they are and prevented. Folks like that I would be proud to know.
