From the first instance where we learned that Hisoka was trying to fight the leader of the Phantom Troupe Chrollo Lucifer, one of the major obstacles in his path were the other members of the Phantom troupe, several of whom were formidable nen users, and some are at least comparable to Hisoka's combat abilities. If Hisoka turned against the leader the other members would not allow him the fight, and would run interference.
Most of Hisoka's actions during the Phantom Troupe vs Kurapika arc is motivated by him wanting to physically separate Chrollo Lucifer from the rest of the members, and have a 1 v 1 matchup. Which didn't come to pass, seeing as how
Kurapika sealed Chrollo's nen abilities.
When he did finally manage to weasel out a neutral match out of him, Chrollo insisted that it take place in Heaven's arena, after he had enough prep time. During their match, Chrollo used several of his new abilities, stored in the dictionary. Furthermore, he borrowed abilities of fellow troupe members Machi, Shalnark and Kortopi, and involved the crowd gathered in the arena as disposable pawns, to essentially kill Hisoka. It is implied that these three had further involvement in his loss, seeing how the exact three members were present after the match, to confirm Hisoka's death.
But, after
resurrecting himself using his post mortem nen
Hisoka restrains Machi and declares that he is going to hunt every Troupe member that he will come across.
Shortly after he
confronts Shalnark and Kortopi and kills them with ease; decapitating Kortopi, and leaving Shalnark's corpse as a macarbe display for Chrollo.
While it is not stated outright, it is implied that Hisoka came to the conclusion, that as long as the limbs of the spider are present, he would never get to have a true 1 v 1 with chrollo.
It is also possible that Hisoka saw Chrollo borrowing the troupes abilities during their match, as them 'intruding' on their duel. Despite being a murderous psychopath with a fetish for fighting strong opponents, Hisoka has his own set of (twisted) code of conduct. Somewhat similar to a perverted version of the 'warrior's way'. Which is part of the reason why he admires fighters like Gon, who value the agreement between fighters and comes at him with no underhanded tactics, and nothing held back.
As soon as he was revived, his mind was already planning their next duel. Realizing that the other Phantom members are always going to be an obstacle, he decides to eliminate them all, before going after the head of the spider. Plus, by going after and killing the exact 2 out of 3 members from whom Chrollo borrowed abilities, and thus 'intruded' on their duel, he is sending a message to Chrollo. That being, 'you had them interfere in their match, and now your actions have led to their deaths'. This will work, as we have already seen how, despite being sociopathic mass murderers with no morals, the Troupe members care for their own, and would go ballistic when a member is harmed.
Happened when
Uvogin was killed, and same thing happened now. Seeing as how now, the entire troupe is abroad the Kakin expedition ship to the Dark continent. I would go as far as to say that, Hisoka's managed to confine the notoriously slippery phantoms in one location, with little chance of wiggling their way out, or escape.
Much like Rorsharch says in Watchmen, "I'm not locked in here with you, you're locked in here with me"
Personal Note: I would be ecstatic if the successor arc concluded with Hisoka having curb stomped, most if not all spiders, especially Chrollo. Go for team Hisoka. (I know that rooting for a psychopath killer over some sociopath career criminals might not seem that good of a position to take, but what can I say.)
