I know that this obviously isn't representative of all Skakdi, but Zaktan's experiences during the Dark Hunter/Makuta War and in Mangaia around 2003 (since there's no internal dating system for G1) seemed to give him a pretty genuine sense of respect for Teridax. Of course, despite knowing what the Antidermis was, he never learned that the fellow had suggested the whole "Mask of Life" bit to him, as you mentioned, so that certainly may have changed things.
The Piraka themselves might not be the most representative examples here, though it's unfortunate that we didn't see any other Skakdi, sans Nektann, in any canon media. After all, they were Dark Hunters, and while things were always pretty rough between the Hunters and the Brotherhood, they were especially bad in the years after the events of Time Trap, when the news that Teridax had killed and eaten a couple of Dark Hunters made its way to the Shadowed One. Just off of that, you'd think that any Dark Hunters, former or otherwise, would be a little anti-Makuta.
