Should we change human nature ? Definitely , if the change would mean greater good for the greater number . For to see wrong , and the need for change , and do nothing would be to commit a ' sin of omission ' - Mark Twain's ' silent lie ' .
Can we change human nature ? Yes , if the benefits of the change / the consequences of not changing can be brought to their attention . For man is reasonable , and knows exactly which way his bread is buttered , even  if the inertia of doing things a certain way prevents him from seeing it for himself . That has been the story of civilisation - a few change , and change the many , often using technology to help them on their way .
On a less cynical note , I vehemently disagree that it is our " snake brains " which make us gravitate towards evil much more readily than to good . That the power of the negative is much more powerful than the strength of the positive is a fact of life rather than of human nature . If we had a predisposition to evil , there wouldn't be a phrase in the English language telling us to " appeal to the better nature " !
