My dad stabbed himself 4 times and threw himself off a bridge, is he going to Hell?

No, God will see that his suicide was very imaginative and will let him in on style points.

A person does not stab themselves in the back and then jump off a bridge. Your father was murdered.
I am so sorry. If a person was to commit suicide, they wouldn't stab themselves in the back unless they were trying to frame somebody for murder. They wouldn't likely have been able to jump off a bridge either.

He stabbed himself in the back 4 times.....ummm okay.

Let God sort that out as He alone knows the condition of your father's mental state.

How does someone stab themselves in the back...

Note the logical people pick up on the parts that don't make sense. While others just focus on the hell part and seem to miss it entirely.

"My dad stabbed himself 4 times and threw himself off a bridge, is he going to Hell?"

If the river flows into Hell, Michigan, then it's possible.

If you are talking about the mythical cult Hell, which has never been proven to exist anywhere, by anyone, and YOU KNOW THAT -- then why ask a stupid question that you know NOBODY can give you a factual answer about?

You know that about half of the BuyBull-cult christians will say "yes, he will" and about half will say "no, he isn't" ---- so why give a goddam about what the cultists say?

The fact of the matter, God is in control of everything and if your dad was a child of God, and if God saved him before he died then he is in heaven with God, so let God handle that, and give God all of your worries because God will wipe away all of your tears.

First of all, I would like to offer my sincere condolence to you and your family for the loss of your father. Please take comfort in knowing that only God can fully understand the role of mental sickness, extreme stress, even genetic defects, in a “suicidal crisis,” which, the National Observer noted, “is not a lifetime characteristic [but] often a matter only of minutes or of hours.” (Psalm 103:10-14; Ecclesiastes 7:7) Granted, one who takes his own life deprives himself of the opportunity to repent of his self-murder. But who can say whether one driven to suicide might have had a change of heart had his fatal attempt failed? As lovers of righteousness we leave the matter in the hands of a merciful, all-wise God as to any possible future for some of those driven to suicide.

Catholic catecism) =
2280 Everyone is responsible for his life before God who has given it to him. It is God who remains the sovereign Master of life. We are obliged to accept life gratefully and preserve it for his honor and the salvation of our souls. We are stewards, not owners, of the life God has entrusted to us. It is not ours to dispose of.
2281 Suicide contradicts the natural inclination of the human being to preserve and perpetuate his life. It is gravely contrary to the just love of self. It likewise offends love of neighbor because it unjustly breaks the ties of solidarity with family, nation, and other human societies to which we continue to have obligations. Suicide is contrary to love for the living God.
2282 If suicide is committed with the intention of setting an example, especially to the young, it also takes on the gravity of scandal. Voluntary co-operation in suicide is contrary to the moral law.
Grave psychological disturbances, anguish, or grave fear of hardship, suffering, or torture can diminish the responsibility of the one committing suicide.
2283 We should not despair of the eternal salvation of persons who have taken their own lives. By ways known to him alone, God can provide the opportunity for salutary repentance. The Church prays for persons who have taken their own lives.

Make a sincere covenant with the Father that you will always obey all of Jesus' sayings , and then you will be able to do what Jesus did , and get him out of hell and back to physical life . Do you care for him that much ?
