That should be between god and the person who sinned. If you killed some one because you were defending your self or another inocent person then I think that can be forgiven but child molestation that is up to god
The bible saids that no sin is greater then another, and yes our God is a forgiving God, God saids His thoughts are higher then our thoughts and His ways are higher then our ways, if it wasnt for his grace and mercy we would All be in hell, some people dont believe in God, heaven or hell, that's their right,
God may forgive these sinners, but it doesn't necessarily mean they will not pay a price for their crimes. If a sinner recognizes his/her sin and repents, God always forgives (according to his word) but many times there is a penalty to pay, if the person is truly repentant of committing brutal crimes he/she will be provoked by the holy spirit to confess to local authorities and family members and accept whatever punishment awaits them.
There is no sin too evil for Jesus to cast out. It says the Jesus died for all sins even those who don't chose him. And saying he can't forgive a sin is putting him in a box and saying "nope this is something you can't do". God is all powerful right? All sin is equal so stop saying that you are better then the murders because I would almost bet you that murderer Christians are almost always wiser then you. When we fall he just wants to lift us up.
It's important to remember that God is a lover of justice and can also read our hearts. Notice what Psalm 37:28 says, “For Jehovah is a lover of justice, and he will not leave his loyal ones. To time indefinite they will certainly be guarded; but as for the offspring of the wicked ones, they will indeed be cut off.”
Sometimes even after committing a wrong act, a person may have a change in heart. Isaiah 55:7 brings out that God forgives in large ways. However, that does not mean that one is shielded from negative consequences. At Galatians 6:7 it says, “Do not be misled: God is not one to be mocked. For whatever a man is sowing, this he will also reap.”
There is only ONE unforgivable sin according to God and that is blasphemy. Thankfully for all of us God doesnt have the unfirgiving human heart we all have. If God had the same attitude as humans we'd all be lost for good. Like free will, forgiveness is available to ALL people or no one. Its all or nothing. The caveat is that we have to ask for and want it and most people who commut heinous crimes dont think they need firgiveness let alone ask for or want it. Still if a murderer does manage to find God and ask wholeheartedly for forgiveness he will recieve it, just as we recieve forgiveness for our many sins. There is nothing that makes us any more worthy of Gods forgiveness than a murderer.
The only sin God cannot forgive is the sin of refusing to turn to Him and accept His forgiveness. To put it another way, the only sin God can't forgive is the sin of unbelief. We are all guilty, dirty, rotten sinners in God's eyes. James 2:10, "For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. We are all sinners in need of a Savior (Romans 3:23).
Would you forgive your child if he did something really bad? We are all children of God and he will always forgive us, even if we did do really bad things. If you are truly sorry for a sin you commuted go to a priest and God will work through him and forgive you. I am not an expert at my religion (Catholic) I would definetly spent time in the adoration chapel and talk to God. Spend time with him .
God loves us all, and he created everyone, I doubt you would want to punish your own children, but you would have to, God doesn't want to punish us, we all earn punishment by sinning. He loves everyone equally
