The 'wicked' are those explained in this prophecy in (2 Timothy 3:1-5). Notice it mentions a specific time period. I think you will get the sense of it.
"But know this, that in the last days critical times hard to deal with will be here
. For men will be lovers of themselves, lovers of money, boastful, haughty, blasphemers, disobedient to parents, unthankful, disloyal, having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, betrayers, headstrong, puffed up with pride, lovers of pleasures rather than lovers of God, having an appearance of godliness but proving false to its power; and from these turn away." (2 Timothy 3:1-5)
Another prophecy undergoing fulfillment. "And this good news of the Kingdom will be preached in all the inhabited earth for a witness to all the nations, and then the end will come." (Matthew 24:14)
