Violent Nature

From the pang's of birth to the throe's of death when has any in nature experienced true peace? There just happens to be an acceptable amount of violence, but when do we find it,unacceptable? A mighty conqueror on approach turns to one of his commander's and remark's.... "if I walk into this city and kill one person i'm considered a murderer.... but,if I march in and massacre all i'll be proclaimed a great conqueror, go figure......" Yes,go figure.... cause and effect can exact a heavy price the rise and fall of empire's is not a new invention of term's.... When hasn't an indigenous person or for that matter,any immigrant, not feel the sting of exploitation, in any country,at any time in history, slavery from the beginning of time.... Still,as in nature,the animal kingdom continue's through natural selection, since,we human's sit at the top without any real predator's a threat, we find ourselve's preying on eachother becoming our own worst enemy.... I wonder if this is the grand design ??
