A true prophet doesn't delight in competing to reveal scripture. Neither is 'hell fire and brimstone' their first love. But, if you want to know why they're more likely to thunder damnation, consider the following verses and you'll understand their fear.
And the Lord hath sent unto you all his servants the prophets, rising early and sending them; but ye have not hearkened, nor inclined your ear to hear. Jeremiah 25:4 Neither have we obeyed the voice of the Lord our God, to walk in his laws, which he set before us by his servants the prophets. Daniel 9:10
God created man in his own image, in the image of God created he him; male and female created he them. Genesis 1:27 Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man.

Who shall separate us from the love of Christ?
shall tribulation, or distress, or persecution, or famine,
or nakedness, or peril, or sword? Romans 8:35
There is no fear in love; but perfect love casteth out fear: because fear hath torment.
He that feareth is not made perfect in love. 1 John 4:18
But they also have erred through wine, and through strong drink are out of the way; the priest and the prophet have erred through strong drink, they are swallowed up of wine, they are out of the way through strong drink; they err in vision, they stumble in judgment. Isaiah 28:7 Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge. James 4:11 Judge not according to the appearance, but judge righteous judgment. John 7:24 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? 2 Cor. 13:5 And if Christ be not raised, your faith is vain; ye are yet in your sins. 1 Cor. 15:17
Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.

Luke 11:50-51 Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven. Luke 6:37 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. Matthew 7:2 For which things' sake the wrath of God cometh on the children of disobedience. Col. 3:6
Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the Lord:
And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers,
lest I come and smite the earth with a curse. Malachi 4:5-6
He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints. Rev. 13:10 But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble. James 4:6 Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God. Acts 14:22
For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. Ye have not yet resisted unto blood, striving against sin. And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. Hebrews 12:3-8
And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth. Rev. 11:18 And he said unto me, These sayings are faithful and true: and the Lord God of the holy prophets sent his angel to shew unto his servants the things which must shortly be done. Rev. 22:6 ... for the testimony of Jesus is the spirit of prophecy. Rev. 19:10
