Although he made a valid observation about LeLouch, at this point Cuckoo is just trolling. I don't know what Aleksei said, but he's a nazi so who cares?
As usual Gul offers a superior analysis. I agree with him that most of the characters in FFVIII are pretty vague; however, scenario writers make it a priority to develop characters by giving each of them defining crises which reveal the traits stipulated by their designers.
What all these characters have in common, is that they break through simple stereotypes. The aim of ESE is to "break through the mask" created by beta NF, and to reveal the person within.
It is not correct to say that ESE is the last to fight and the first to make peace... that is not their role. Their role is to reveal who is trying to do the world right... and who is just out to make trouble.
Anyway...
