God knows what you're going to do, but He works in odd ways. Why is there a Satan and why is there sin? Because without it there wouldn't be free will, with it there is. You can choose the narrow path to righteousness, or the wide path to destruction.
Yeah, I can't really explain all of it because God purposefully doesn't tell us everything, similar to parents.
Sin isn't like a physical or material thought or object, sin is just imperfection...God is, Biblically, perfect in every single way, so basically not being like God is sin...and we were in his image and like God until we decided to choose sin over Him.
As for Satan....before Adam and Eve, Lucifer was an angel that rebelled against God, because he wanted to be above God and he decided to rebel against perfection in pride and jealousy. 1/3rd of the angels sided with him. That was when the angels of heaven made their choice on what they want to do. 1/3rd of the angels decided to side with Lucifer, and so since that was sin, God created a place of punishment for these "fallen" angels and cast Lucifer and them there (AKA Hell). With that, sin was no longer in heaven, and those that remained worshiped and loved God and remained his loyal servants...the angels we know today.
Satan and his demons, have a personal vendetta against God, I'm sure because we were created in God's image, it made him especially jealous and angry...and therefore sought to destroy humanity and lead them to death and separation from God. So Satan tempted Adam and Eve. Nothing that Satan does, however, is outside of God's knowledge, so it's very possible God allowed Satan to try and tempt Adam and Eve to see if we would choose God over Satan...which we chose the latter of.
Sin entered the world simply because we messed up once. We disobeyed perfection and with the consumption of the fruit our eyes were opened to both good and evil, and we were eternally separated from God because he is only perfect and God.
God punished Adam, Eve and Satan for their actions, and as much as he loved them he was in sorrow and, well read the rest of the Old Testament. Even if you don't believe in it, it's a fascinating story.
Why does He bring people destined to go to hell into the world?
They choose to go to Hell....it's kind of silly in my opinion to say you would rather not live because you're scared of going to Hell, when Heaven is an extremely easy and wonderful choice.
Regardless, he wanted to create companions in his image..and he saw that it was good. God sees procreation as good. He wants people to fellowship and commune with and love. Sadly some don't choose Him, but at least he gives them the choice.
I'm not really sure, I'm just giving my answer.
I feel God has a soft spot in His heart even for them, that He hurts when they are thrown into hell. Why does He let it happen? I don't know.
Of course it hurts him...the Word says that God desires that no man go to Hell, but that all be saved through the knowledge of His Son.
He's good and just, so imperfection is something that is just impossible for God to be with. It can't be with him and He can't be with it. We're sinful, that if God revealed himself completely to us we would die. That's not how it used to be. Souls that choose sin must be punished, because that is just and good. It's just how things work. And it hurts him, but because he's the origin of justice, he will judge all at the end of time. Those who don't accept him will have their last chances during the Apocalypse when he comes back.
To be honest, we don't even know what God does after we die.
It's sort of unknown, but I've had people theorize and say that time is like a ring, going on forever and God can see the entire thing. When someone dies, they go outside the ring, both saved and unsaved, outside the realm of "time" perse'e, and then when judgment happens all souls suddenly appear at that time-period to be judged...and those written in the Book of Life will reign with God in the New Heaven and New Earth for all eternity in peace, joy and fellowship with the Creator.
Lots of ideas, but all we know is that Christians go to Heaven and those who don't accept Christ are punished.
But once they die, does God come and help them? Maybe He does. He loves His children too much to see them perish.
Nope. Sorry, the scripture says "I am the Way, the Truth and the Life, no one comes to the Father but by Me." and "If you declare me before men, I will declare you before my Father in Heaven. If you deny me before men, I will deny you before my Father in Heaven." There's simply no other way to paradise but by Jesus, because he was the only perfect person to die for the sins of the world so we could reunite with God.
