'Do unto others' is a principle that can be applied into every situation.

You might think the situation is too broad or complex etc, but your calorie-guzzling brain can work the many and various context-dependent scenarios out. For every wrong there is a right answer. We live in a moral world.

Luckily, its not your job to sort the world out. You can only work on yourself and ensure your actions are aligned with morality.
