Charlotte Katakuri's strength had unquestionably surpassed Borsalino's in every respect. Since the latter could not defeat Katakuri, he could not protect his family from him either, and could only rely on even stronger veteran powerhouses for help.
But Sengoku and Garp could not catch up to Katakuri once he accelerated. Katakuri could repeatedly launch attacks exactly as Borsalino had said he would when making his threats. Was the Navy really going to keep those two top-tier fighters by Borsalino's relatives' sides at all times to protect them?
Besides, if they truly tore their relations apart to that extent, Katakuri would not necessarily have to keep targeting Borsalino's family. Sengoku's, Garp's, or the families of those other formidable figures could receive a visit as well!
There was simply no way to guard against it all!
At that point, although Borsalino could theoretically still use that move to threaten the BIG Pirates, the latter would have gained another means of establishing a terrifying balance of terror. The scales would inevitably tip in their favor.
Just like the motivation behind the United States and Soviet Union desperately increasing their nuclear warhead stockpiles during Earth's Cold War.
