Actually, there’s no need for much speculation at what He will do on His return to this “ball of dirt”. Revelation is quite clear on both when He returns as well as the consequences of a His breaking the seals shortly before that.
As for the time of His return, He says something, or the sword that comes from His mouth, and everyone following the beast or the FP will be slain.
Revelation record the Lord’s wrath in the time leading up to this and it would seem reasonable that this outpouring will be for reasons not unfamiliar to Jews in OT times: to bear witness that He is Lord and to inspire those still able to confess Him.
One needs to realize that the times we are talking about are at the very end of any possible Romans 1:18-32 situation ... or a culture that is polluted as polluted may yet be, so it takes some “shouting”, in the form of real wrath, to reach those defiled by such a polluted culture (but not personally reprobate, arguably because they had limited knowledge of Him beforehand that they rejected, you know, the sort of thing that sets off a Romans 1:18-32 process of which the embracing of homosexuality is a symptom of a disease well progressed, not a root cause).
So, given that we see the effects of a Romans 1:18-32 process all around us even now, it seems reasonable that most to all of those who have been turned over to reprobate minds, or will yet be, who endure till His actual return will have probably also taken the mark too.
Those will all be slain.
Yup.
As stated in my follow up comment to my first comment, my PS was not well expressed.
Yup. My last sentence in the PS was a goof up.
