Kabuto was quite cautious, but he also had a crazy side.
For example, in the original story, when Orochimaru fought Jiraiya and Tsunade, Kabuto actually dared to take Tsunade on alone!
Although Tsunade's fear of blood kept her from using her true strength at the time and left her hesitant to act, most people would probably have been too frightened to fight just from hearing her title as one of the Sannin.
Who else would have given Tsunade as much trouble as Kabuto did?
In the end, if Naruto, with his protagonist's plot armor, had not forced his way in and delivered a "fatal" blow to Kabuto with a combination of talk-no-jutsu and the Rasengan, helping Tsunade overcome her psychological trauma...
Kabuto might have earned the epic achievement of single-handedly killing Princess Tsunade of the Sannin.
Just how strong had Kabuto been back then?
At the absolute most, he had only been on the level of a Special Jōnin.
Later, after inheriting everything Orochimaru left behind and turning into a little dragon man, he reached his peak and dug up graves all across the Shinobi World, creating an Impure World Reincarnation army beyond even Orochimaru's imagination.
That crazy side of him had even left Obito somewhat shocked and wary!
Originally, this secret research base beneath Otogakure had contained no mechanical traps. Orochimaru had disdained such things.
But after Kabuto took over, the first thing he did was install a large number of mechanical traps to ensure his own safety.
As a result, on his way down, Shinji went through volleys of arrows piercing his body, slashing blades and chopping axes, spikes beneath his feet, and boulders smashing into his face...
Often, there was simply no way to dodge!
Even an Elite Ninja might have been injured or killed.
