This sounds good but it is definitely not biblical. Philosophy is no substitute for Bible truth.
At the time of creation, God did make everything good -- indeed perfect. However God also gave men and angels free will, and because of their disobedience they became sinners and rebels. Now the sin nature indwells every man, and Satan and evil angels continually incite men to sin.
Here is the Bible truth:
13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: 14 But every man is tempted, when he is drawn away of his own lust, and enticed. 15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. (James 1:13-15)
Without the New Birth and the indwelling Holy Spirit, men do not have to power to turn away from sin and turn to righteousness.
This is not according to Scripture: For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. (Rom 7:18)
This too is not according to Scripture:
21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, 22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: 23 All these evil things come from within, and defile the man. (Mk 7:21-23)
