Use the adverb amorally to describe something that's done without any thought about whether it's right or wrong. If you wonder why anyone would buy the more expensive "fair trade" coffee, you probably make buying decisions amorally.
When you do something amorally, you do it in an ethically indifferent way, without stopping to contemplate whether it's good or bad. That doesn't mean, as with the word immorally, that what you're doing is wicked, it just means that you're not concerned about the moral consequences of your actions.
