Judas was acting freely. Point of this betrayal was to fulfill scripture. The fulfillment of scripture is proof of who Jesus was. OT scripture is what Peter used on Pentecost to prove to the people that the man they crucified was Jesus the Messiah.
2. How do we know that we are being truly inspired by the Holy Spirit, as opposed to being decived by our own wishes, or even a false spirit(demon)?
One thing I have come to the conclusion about this question is (boy I'm fixing to start something here, but remember you asked:) If you can imagine you or anyone else being able to loose their salvation, you are NOT being led by the Spirit. I know without a doubt, 100%, that I am going to heaven. Why? Because I know JESUS is going to keep me saved. He can't loose MY salvation. 2 Tim. 2:12...for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.

You know more than Paul or Christ then.
What if I can imagine people who think they are saved losing what they think is their salvation?

So 1Cor 9:27, and 2Cor 13:5, Not to mention Ps 51:1-19 where all written without the HS?
