I agree. Humans are innately good, and can only seek what is right, but do not always know them from "bad and wrong". To choose "evil", even for it's own sake can only be done out of misplaced faith that it is the "good and right" choice to make. Christ, as did The Buddha, taught 'sin', which is just "spiritual error" of the ego, as another word for 'ignorance' (both figures are considered to be examples of man without sin and ego). We are not born "sinners" because we're "wicked" and "evil", but because we don't know any better. If we did, we would.
Ignorance/sin, is a byproduct of freewill. Had God made us already knowing everything, there'd be no point in giving us the option to choose. Only God can be omniscient. The Lord is 'All-Knowing' by way of 'Being All'; therefore He is, 'The Almighty!' Adam and Eve failed to recognize that knowledge can only belong to God, which led them to being deceived into committing "Original Sin". This resulted in their mortal existence in the earthly realm, along with the rest of humanity to follow.
The human mind and intellect cannot know all there is to possibly know, and can only, at best, "approximate", and "know about". We tend to get answers that only seem to lead to evermore questions to be asked, because "knowledge only begets evermore knowledge". This is why it is said, "the wise only know that they know nothing", as Socrates confessed, nearing the end of his life. 'To know', means identifying with and being the known. Knowing about China is not the same as what it means to be Chinese, or going there.
Without freewill, we'd all be stuck on the level we start out on, with no chance of advancing. Our material world is expressed as "variety" and "diversity", which are suitable for the capacity to choose. Out of His Unconditional Love, it is God's Will that we have 'freewill' so that we may choose Him on our own, which demonstrates that He does not rule by force. Love that has to be "forced" cannot be 'Love' at all. God did not prevent Adam and Eve from committing Original Sin, because it would had robbed them of their opportunity to choose for themselves.
