That is the teaching of Scripture Winman. If you don't like it take it to the Lord in prayer. Perhaps you can get a "do over"! In the meantime while waiting for that "do over" you should meditate on the general condition of mankind as revealed to the Apostle Paul by God:
Romans 1:19-25
19. Because that which may be known of God is manifest in them; for God hath shewed it unto them.
20. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21. Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22. Professing themselves to be wise, they became fools,
23. And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24. Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25. Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
In this passage God through Paul does not talk of the total depravity of mankind. That is addressed in other Scripture. He, God, does show that all mankind will sin. You can blame it on a natural tendency to sin or whatever but God tells us just like it is!
