It doesn't matter because verse 43 clearly states that the fire shall never be quenched.Okay, let's take these three verses you cite below.
So, you want to take this verse literally? Then I'll assume that Jesus really wanted us to cut off our hands and feet or pluck out our eyes (verses 45, 47).
That said, are you aware that the entire verses of 44, 46 parts of verse 45 and 47 are spurious? Meaning that they do not appear in the Codex Vaticanus and the Codex Sinaiticus.

I guess we could segway into why we shouldn't value the Codex Vaticanus and the Codex Sinaiticus over the Textus Receptus but we will leave that for another time.
