I don’t actually believe in right and wrong. It’s all a matter of perspective.
I do have a sense of right and wrong; I have a moral compass – I just don’t believe that my (or and other organism’s) moral comapass orignates from anything more than arbitraty fluctuations in a highly complex evolutionary landscape.
Think about this: Is it morally wrong to kill potntially deadly bacteria by cooking your food? No. Unless, of course, you happen to be that bacteria. Then you might find it quite inconvenient being boiled alive and you’d probably think – if you could think, of course – that being boiled alive as a result of doing nothing than minding your own business was, well, quite wrong.
