How do I know what's good and what's evil?

Good and evil are two very different things. A good person is trustworthy and honest when honesty truly matters. A good person respects the rights, differences of taste and personal space and property of others. A good person cares about others and acts to help his or her fellow human beings. An evil person is morally bad or wrong. Always causing ruin, injury or pain. They are characterized by or indicating future misfortune. They are blameworthy of bad by report. They are characterized by anger or spite. I know the difference between a good and evil person by the way they dress. Evil people generally dress wearing dark coloured clothes and do not like showing their face. Whereas a good person generally dresses wearing bright clothes. I also know the difference the difference by what they say and how they speak. Evil people generally swear while they speak and do not sound very nice or confident. Good people generally do not swear while they speak and they speak with confidence. I also know the difference between good and evil people as a gut feeling. Although a gut feeling is not always correct.
