In Revelation 21:8 Did John mean by “all liars” the previously mentioned in the same verse?

Revelation 21:8 (KJV);

8. But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.

Did John mean by all liars the previously mentioned in the same verse, i.e: the fearful, unbelieving, abominable, murderers…etc?

I mean that all liars not the eighth category, but includes the previously mentioned seven categories.

And if so, how a murderer be a liar?!, How a whoremonger be a liar?!

I hope you understood what I mean.

And why the last of the Bible (Revelation) condemn lying?, Look Revelation 21:8,27 and 22:15.
