Here is the description:
Hojo is the archetypical mad scientist. To him, everything in life is nothing but mere experiments, not caring about the well being of others when he puts his hypotheses and theories to the test.
He is arrogant and condescending, referring to people as "test subjects" and not bothering to learn their names unless, like Sephiroth, they prove exceptional.
Hojo's only desire is the pursuit of science and understanding of the Planet, willing to go to any lengths to further his knowledge. He performs many horrific experiments on unwilling human subjects with no regard for their well-being, and eventually even experiments on himself.
Even when his actions put the city of Midgar at risk, Hojo considers it another price to pay for his experiments.
So what do you think?
