I don't get how you can consider someone a good person when they engage in riba, drink, believe in democracy, hyper sexualise women, promote STD's, accept suicide, and don't even thank the one who created them or spew lies about the creator. The last one is by far the biggest crime. Shirk shows complete ingratitude to Allah, the one who gave you life purely out of mercy. Allah didn't need to create you, you only exist because of Allah's generosity and mercy. If you have been told of the Haq and don't follow it, you're the worst of creation.
