Best way to counter this argument and though I do agree that we should try to forgive people regardless of the wrong they did, it honestly doesn't matter when you think about Deities Judging us for our actions & words.
God/Jesus are apparently infinite in forgiveness, compassion, mercy, and love. But then that is all proven wrong when you think of Hell, a realm of eternal suffering, anguish, pain, sorrow, and absolute negativity.
I wouldn't even send Hitler to Hell, nothing any of us do could equate to an ETERNITY of horrific suffering, pain, and sorrow.
The philosophy of Forgiveness from Jesus makes sense on a mental level, cause the more you hate someone, you're just causing yourself more grief, more suffering, and for many they'll use drugs to escape that suffering. But ultimately when you think of Hell, that doesn't in any shape or form sound like forgiveness, it sounds like pure vengeance and no crime that we commit, no matter how numerous, even if we someone managed to break every law according to man & god and did each of them a million times over, that still wouldn't fit the punishment of Hell.
MAYBE for 100 years or 500 at the absolute most, but Eternity? That is countless eons (eons = millions of years) of never ending torture.
If God/Jesus is a ACTUALLY serious about Forgiving, then Hell wouldn't exist. And personally, I refuse to believe that a Deity that is suppose to be our father, that loves us with all his heart, and wishes us to be the best that we can strive to be, would send us to a realm of eternal horrific torture & all around evil for not being sorry they stole bread to survive.
That doesn't define a Good God, that defines an Evil Hypocritical & Egotistical God.
And the ultimate bull of a quote from Jesus "I never knew you, depart from me, evil-doers" that's him saying that to people who believed in him & accepted him as their lord & savior, and he is suppose to have the same omniscience as God - For him to actually say that makes him a liar & a deceiver, even the bible CLEARLY states that Jesus knows everything that his father knows, and if both his statement & that bit about him are true, then he is a liar.
Personally, most of what the bible says honestly sounds like complete rubbish - only man can be inconsistent & contradict itself that damn much, especially when its suppose to be God's own words and he is suppose to be "Perfect" along with his son, Jesus, it makes absolutely no sense for a Deity to not notice the numerous contradictions in this "Holy Word".
The book may have been INSPIRED by God, but it clearly was not written by God, and most of it just feels wrong to be considered "the good book".
Ultimately, your opinion of what Jesus preached. If he really meant it and truly will forgive everyone that has ever been, ever was, and ever will be, then Hell doesn't exist. If Hell does however exist, then honestly he was lying.
You can't truly forgive someone then torture them for the rest of their life because of the very thing you forgave them for. If you do truly forgive them, then you'll live & let live. Torturing them says the exact opposite. Actions speak louder than Words, this also applies to God & Jesus.
