You make a good point. But perhaps Dr. Clark performed some kind of experimental testing on SF on Zero's orders, which is why SF wants to kill Zero. I initially thought that the photo was one of Zero in his old age, but Dr. Clark appears to be fairly young in this photo, so I immediately ruled that out. I do think that whatever Zero did to piss of SF, it had to be drastic for SF to want to kill Zero.
