I understand that's their attempt at justifying bad writing.
The reality is that following basic safety protocols in any situation is a lot cheaper than wasting crews and spaceships, let alone labs next to where you live that are handling anything dangerous.
They don't even follow the basic protocols of a high school lab. Okay, you've left (multi-billion dollar) kids in charge. Maybe monitor them closely? Most of the time, they are unmonitored, or being monitored by a clearly and openly hostile synth.
It's the lazy horror trope of people doing dumb things because the plot requires it.
How hard would it be to write that final scene, for example, without having the hybrid kid forget that he has super strength and still put him in jeopardy?
