Relativity of ethics

Relativity of ethics is the concept that something that is deemed good might not be good for everyone.

The word good is a relative term. For instance, on the death Star Luke and the rebels went out to blow it up but, what of the imperial officer coming to work to feed his newborn baby. Was Luke doing good when he blew them all up or was the imperial officer doing bad when coming to work? I comes down to framing. The only 100% good is what is common for all. We all stand on the earth, we all breath the same air, if someone truly thought their aim was to do good, they would have to be involved in protecting the environment.
