If one has impure thoughts, such as; rape, murder, suicide, and other severely bad thoughts, will they go to hell even if they never act on them? Why would someone have thoughts like this so often? What's wrong with me? Is there a way to fix this that involves prayer?

You can pray about it but there's a difference between having a thought and dwelling on one. If you simply have an idea that pops into your head, that's normal. There are dark forces that are constantly trying to distract us from what we should be focusing on and yes prayer is the answer here. Ask the Lord to help you to overcome those thoughts and you shall.

Thanks for your insight, I've been thinking about this a lot lately and it has become a problem for me.

also talking with others believers will help u clear up ur mind

there are no unpure or pure thoughts
these are simply judgmental points of view.

And who would worship a god that only asks love in return for not sending us to hell.

God loves you every day, even if you may not realize it.

theres alot of demonic junk that goes on, and even though i have been saved for a bit now, i still do have demonic stuff over me.
People dont like to talk about this too much, but the fact is that the spirit realm is all around you, and that what your feeling/thinking/whatever is prolly a result of some weird
evil force.

Pray it off --- something like:

In the name of Jesus i command every foul spirit and demon to go to the footstool of Jesus, and i claim my freedom by the blood of Jesus,
when He died on the cross, you were stripped of your power and i demand you to leave right now, i ask you Jesus for warring and ministering angels
to drive this out of me, and for the blood of Jesus to cover me, and declare every spirit of hate and perversion to leave in Jesus might name,
Amen

You'll find peace of mind when you find the Lord.

you sir, are a psychopath
