Atheists, tell me, a Roman Catholic: why should I become an atheist?

[Chas]

I definitely can see how many consider the Christian God to be morally horrible. Obviously (and expectedly) Christianity teaches us that God is the complete opposite of that...anything he does that we as humans perceive as evil or wrong supposedly has a "perfect" justification for it. I won't deny that this seems like it could merely be a convenient way to justify claims that God is purely good -- but of course growing up with a mind conditioned to interpret every single one of his actions as absolutely perfect makes it hard for me to accept the opposite. I'm sure this is at least partially why so many theists are so confident in their faith in God's goodness, regardless of if God is real. The theist mind is trained to immediately interpret events in favor of God/their faith...whether their interpretations are rational or irrational.

God's "need" for love/worship again seems to be in accordance with his supposed nature. He wants us to worship Him so that we may grow closer to Him, strengthening ourselves morally by obeying Him. Why exactly God would send us to Hell for not sufficiently worshipping Him (rather than making it optional to live "immorally" without the consequence of Hell)...I'm not sure, and I don't even know if any theists I ask will have an answer that extends past simply claiming something like "we don't know, but God has a perfect reason."  

As for Heaven, I've had thoughts in the past about how we'd feel knowing so many people would burn in Hell for eternity. Christians justifications claim that in Heaven, even though we can't understand it right now, we'll be completely without negativity/negative emotions. We'd fully understand God's reason for sending so many people to Hell and be able to move on. Of course, this is based off of the basic ideas of Heaven and doesn't necessarily support the idea of Heaven.

Instead of trying to work those things out, go back to square one and consider the fact that there is no actual evidence of the existence of gods or hell or heaven.
You are wasting energy on things that likely don't even exist.
