O.o kill it of course. Only... I could never do it because I don't kill even flies...
And how in the hell could a monster from Greek mythology make our life better?!!!!! Or... what is a chimera if not that? O.o
Ok, ok... it's MADE, but... come on!!! Serve humanity? We should start helping ourselfes a bit more... We should start caring more about what is happening around us. And we should stop exploiting nature that much and playing with it so much it will have it's revenge sooner or later. Aint chimera a monster? It could easily just kill us off... So could any other creature come out to have "side effects" as genetically moddified beef meat has its side effects.
God's acts carried out by us? I dunno.. are you sure god would do so much just to help a species witch is slowly destroying his master piece? O.o by brinign in more pain and misery to other creatures?
