Are Humans confused as to their own free will?

Typically, this is something I explain in the religion and spirituality section, so forgive me for making reference to God and faith.  I can understand how it can turn people off, but it's what I am most familiar with in explaining my view on the subject. I, generally agree with your premise, but I think it's all for a greater purpose.  For freewill to work, there has to be some degree of uncertainty for outcomes, for choice to be possible.

Jesus, as did The Buddha, used the word, 'sin', which is just "spiritual error" out of ego, as another word for, 'ignorance' (both figures were without sin and ego).  We're not born sinners because we're "wicked" and "evil", but because we don't know any better; if we did, 'we would'.  Humans are born only knowing how to choose good and what is right, but are limited by not always knowing what they are.

"Ignorance/sin" is a byproduct of inheriting freewill.  Had we been made knowing everything, choice wouldn't be a possibility for us.  Without freewill, we'd all remain stuck on the level we start on, with no chance of further advancement.  The variety and diversity of our world is suitable for the capacity to choose, and allows the potential for positive, negative, and neutral options and outcomes. 

Out of God's Unconditional Love, it is His 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; thus He does not interfere without our consent.  If God prevented Adam and Eve from committing "Original Sin", it would had robbed them of the opportunity to choose for themselves.  

Yes, people often make choices carelessly, but I don't think it's correct to say that humanity's ability to make choices is their downfall.

As I see it, if a being has the ability to imagine more than one possible course of action, that being has free will.

I guess you are thinking about people that choose to drink and drive, or engage in some similarly risky or self-destructive behavior, but more often than not, the choices that individuals make are their salvation. I'm thinking about everyday choices that keep us out of danger, like stopping at red lights, putting warm clothes on for cold weather, and umpteen other simple things that we barely think about, but that we could imagine not doing. 

If you are thinking about humanity as a whole, I think free will is our only chance for salvation. If we mindlessly pursue our desires, without the thought of doing otherwise ever crossing our minds, we fail to utilize free will.

We succeed in exercising our free will when we consider our actions, recognize that they will have detrimental consequences, and subsequently imagine and opt for alternate courses of action.

Sometimes, you have to use what is called the "free-will override". This means that by your own free will you will not commit that sin or do that bad thing you want to do. You exercise your free-will to do good. You purposely do something better or refrain from doing the bad by your own choice. Free-will is proactive.

People need internal sympathetic opposites. That might be emotional and rational dispositions. At some point in our development we learn to integrate more and more of our opposites. This affords us control and power. As we are less the slave and more the master.

We be what we need to be. Just finding that being is the key,

I think humans are the universe and universe is determined. Free will is not defined or proven, it isn't compatible with the scientific method because science demands you define your terms/question. Free will fails the first step of the scientific method because it's undefined.

Would you accept this definition?

"Free will is the ability to have acted differently"

It's grammatically incorrect, but it's the least controversial as far as im aware. You tell me: how could we have acted differently? Do we choose anything about ourselves? Human behaviour is just a fact about the universe, it's either determined or random, in either case there's no room for free will.

The laws in this country leave room for those who are of free enough will to take responsibility for their choices if they want.  We don't always have to blame someone or something else for our behavior.  

You generalise which is immediately dangerous when dealing with humans. For my part I'm perfectly clear and I take full responsibility for the choices I make and the consequences I may suffer. If you wish to abrogate your responsibility to others then it raises the question of who can be relied upon to make your choices for you. 

I would suggest that if relying on others you need to be competent to judge their motivation, honesty, and reliability. But you already want to abrogate this responsibility because you're not ! So round and round in circles you go and confusion and delusion results.

Sometimes our choices are made on our behalf by those in power. Sadly our systems of selecting these people tend to favour the most unsuitable individuals.

There are always those who are ready, willing, and able to exploit the confusion and gullibility of those who make themselves vulnerable, but that's their choice

Nope. We don't have free will,

There is an infinity of Good among which to navigate and develop; that is God's hope for mankind:  increasing expression of God's Love, Light, Truth, and so on.  The ability to make such choice is Godlike.  The perversion of Godly awareness, sometimes called "free will," is post-Garden egoism, rather than One Mindedness, Oneness.

If a human is her own worst enemy, that reflects that she has not put off the old woman with her deeds, has not become the new woman in Christ, Truth, i.e., submitting to God's will, which is always good, and reflects the tender Love and care of a Parent for Her Child.  "Angel on one shoulder, devil (fallen angle) on the other" is the caricature.
