The fact that the Cruelty class feature does not have similar text to the Touch of Corruption
This ability is modified by any feat, spell, or effect that specifically works with the lay on hands paladin class feature. For example, the Extra Lay On Hands feat grants an antipaladin 2 additional uses of the touch of corruption class feature.
means that the Extra Mercy feat cannot be taken by an Anti-paladin.

heheh, better not be for pfs. there's no antipaladins for PFS players.
I must admit that I don't play PFS and I am not familiar with all the specific rules for them. But, I guess if I had thought it through I know evil characters are not allowed in PFS, so no AntiPaladin would seem a no-brianer.

We must respectfully submit that this may be more of a grey area. As quoted above regarding touch of corruption:
"This ability is modified by any feat, spell, or effect that specifically works with the lay on hands paladin class feature. For example, the Extra Lay On Hands feat grants an antipaladin 2 additional uses of the touch of corruption class feature."
Emphasis my own.
In the language on cruelties:
"At 3rd level, and every three levels thereafter, an antipaladin can select one cruelty. Each cruelty adds an effect to the antipaladin’s touch of corruption ability."
It seems pretty clear that cruelties ARE an "effect" and thus possibly modified by feats.
In our Way of the Wicked campaign, we went so far as to allow my Antipaladin to take the "Word of Healing" feat. The title sounds counter-intuitive, but it's just so lovely to reach out 30 feet with a paralyzing ebon flame. Disagree at your peril. She may find your lack of faith.... disturbing.

I will counter by quoting the same bit of text "...or effect that specifically works with the lay on hands paladin class feature..."
Extra Mercy feat requires the mercy paladin class feature. Not the lay on hands paladin class feature. So by RAW it cannot be taken since an anti-paladin does not have any mercy.
Even if it could be taken, an anti-paladin taking the Extra Mercy feat makes very little sense:
Select one additional mercy for which you qualify. When you use lay on hands to heal damage to one target, it also receives the additional effects of this mercy.
If one substitutes 'mercy' with 'cruelty' and 'lay on hands' with 'touch of corruption', this feat only functions when the touch of corruption is used to heal. Which is a little useless.
That said, I would allow a new feat (Extra Cruelty has a nice ring to it) especially designed for the anti-paladin which does pretty much the same thing, except it's on harming rather than healing.
