Can I join a cult?
Why would you want to join a cult?
To achieve the ultimate goal of helping the humanity.
Cults are proven to be evil and misleading to people. You're going be disillusioned with them eventually. I understand you want to do good to people but joining them is not the way,
Yes! I have to join a cult to help humanity.
If you want to help humanity, wouldn't you want to join a non-profit organization instead? If you join a cult, you might get labeled by society and people might actually want to avoid any association with you.
