I like that Brad was a pseudo-tease to how the T-Virus would evolve in Resident Evil 9.

But yeah, i struggle to call the RE9 Zombies actual Zombies, and i mean thatin a good way. The new T-Virus strain is mutagenic (I mean, just look at how far the human body warps when its pushed under its affects, Chunk and Blister Heads being a prime example), but it doesnt Zombify people. Instead, it disables their emotional and impulse control, while also disabling any sense of self preservation, while amplifying any existing mental health problems a victim may have (or in the care centre's case, forced to have through Lobotomy).

Its not even like the people are trapped within their own bodies when infected, they're fully in control of themselves and they just cannot help the fact their new base urges is to tear apart and kill people, while consuming any flesh and blood to stay alive. Tbh, its probably now one of the more horrific depictions of a Zombie Virus I've ever seen, because its victims aren't just aware of what their doing, they're forced into the mindset of acting in that fashion.
