DECEIVING AND BEING DECEIVED: planontes (PAPMPN) kai planomenoi (PPPMPN):
leading astray and being led astray (Wuest)
mislead people & are themselves misled (GWT)
having been deceived by Satan (TLB).
Deceiving (4105)(planao [word study]) in the active voice (the first use in this verse) means to go astray, wander, roam about and can describe physical wandering (English word - planet) but is often used figuratively of leading others away from the truth and into error and thus to deceive them. It means to deliberately cause someone to regard as correct something that is really wrong.
Vincent says that the verb planao spoke primarily of those who wandered or roved, such as vagabonds, and then came to mean deceivers or seducers.
Webster's 1828 Dictionary says that the English word deceive (from Latin decipio - to take aside, to ensnare) means to mislead the mind; to cause to err; to cause to believe what is false, or disbelieve what is true; to impose on; to delude.
Robertson remarks that...
The tragedy of it all is that these seducers are able to deceive others as well as themselves.
Being deceived is in the passive voice which describes the subject (the imposters) as being led astray themselves and the present tense indicates this is a progressive or continuous deception. So on one hand the imposters actively lead others astray from the Truth (the Gospel of Jesus Christ) by either their conduct, speech, or writing but on the other hand their just reward is that in the very process of deceiving they are being led astray themselves!
As MacDonald says...
After having peddled their lies for so long, they would actually come to believe them personally. (MacDonald, W & Farstad, A. Believer's Bible Commentary: Thomas Nelson or Logos)
Error feeds on itself or as our Lord Jesus taught...
everyone who commits (present tense - as their habitual practice) sin is (present tense - continually) the slave of sin. (John 8:34)
Solomon wrote that...
His own iniquities will capture the wicked, and he will be held with the cords of his sin. (Proverbs 5:21-note)
Peter spoke of the entrapping effects of sin writing of false teachers who were...
promising them (their hearers) freedom while they themselves are slaves of corruption (phthora = disintegration, decay or rotting - like organic matter, pictures the "rotting" of morals with of loss of integrity as a result of a slow decay of their soul!); for by what a man is overcome (perfect tense = speaks of permanence of this state) , by this he is enslaved (perfect tense = speaks of permanence of their enslavement). (see note 2 Peter 2:19)
Bengel adds that
He who has once begun to deceive others, is the less easily able to recover himself from error, and the more easily embraces in turn the errors of others. Who or what is the power or influence leading them astray?
Matthew Poole comments they are...
deceiving others, and being left by the just judgment of God to deceive and ruin their own souls.
Expositors comments
Those who deceive others impair, in so doing, their sense of the distinction between truth and falsehood, and thus weaken their power of resistance to self-deceit and to imposition by others. (Nicoll, W Robertson, Editor: Expositors Greek Testament: 5 Volumes. Out of print. See Google Books)
Peter describes a similar spiritual dynamic in the last days mockers warning us to...
Know this first of all, that in the last days mockers will come with their mocking, following after their own lusts, (see note 2 Peter 3:3)
In the Revelation John adds that
the great dragon...the serpent of old who is called the devil and Satan... deceives (present tense; active voice) the whole world (see note Revelation 12:9)
