1 Corinthians 12:2-3 You know that you were Gentiles, carried away to these dumb idols, however you were led. Therefore I make known to you that no one speaking by the Spirit of God calls Jesus accursed, and no one can say that Jesus is Lord except by the Holy Spirit.
Some suicide can be demonic. The Holy Spirit does not drive people into wild compulsive acts. He empowers people for ministry. He does not overpower.
Moses was a murderer...and so was the Army of Israel when they followed God's orders:
1 Samuel 15:2-4 (New International Version)
This is what the LORD Almighty says: 'I will punish the Amalekites for what they did to Israel when they waylaid them as they came up from Egypt. Now go, attack the Amalekites and totally destroy everything that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.' "
At what point is one forgiven for their sin? Shall we sacrifice Yeshua over and over...each time we sin? The sin of tomorrow is already forgiven! Praise God for that! There is nothing you can do to lose salvation if you have truly received it...Yeshua said that he will not lose one sheep that his Father has given him. If you are a true believer...and you commit suicide...you WILL be in paradise.

That does not fall under the same category.
Capital punishment and judgment is God ordained.
Consider
Numbers 25
Numbers 25:7-11 Now when Phinehas the son of Eleazar, the son of Aaron the priest, saw it, he rose from among the congregation and took a javelin in his hand; and he went after the man of Israel into the tent and thrust both of them through, the man of Israel, and the woman through her body. So the plague was stopped among the children of Israel. And those who died in the plague were twenty-four thousand. Then the LORD spoke to Moses, saying: "Phinehas the son of Eleazar, the son of Aaron the priest, has turned back My wrath from the children of Israel, because he was zealous with My zeal among them, so that I did not consume the children of Israel in My zeal.
The judges of Israel were required by God to kill the apostates (Numbers 25:5).
And concerning Moses, he saw an Egyptian beating a Hebrew, a servant of the Egypt, and one of his brethren.
In the sight of Moses, this was cruel treatment for the Hebrews were not mere slaves, but servants of the Egyptians. So Moses killed him. However, this was not a desire to take a life. This was a desire to protect a person who was being treated like a slave. Jesus was beaten and was a servant of God, was He not? If you were living in His time, you would desire to help Him, would you not?
Accidental killing and accidental suicide, capital punishment, judgment, and defending yourself or another person will be pardoned and is not a sin.
Suicide will not be forgiven and is sin for it is a compulsion and desire. God does not drive people into wild compulsive acts. God is gentle and kind. For God leads people (Matthew 4:1; Galatians 5:18; Romans 8:14).
Is He not a shepherd and we are His sheep?
