>let's kill them all except the baby and one parent
Actually, as mentioned, both parents were supposed to be kept alive.
Also, the FEV they used was tailored to Shaun's DNA, making anyone else but his parents, who shared similar DNA, nto a viable backup.
They also had all the records of Vault-Tec(which is how they found out about Vault 111, and Shaun, in the first place, and would thus know of any medical issues they had)
>we will accomplish this by fucking with the outside world constantly like poking a bees best
If you listen to the Director's recording from back during the time of the CPG and the Broken Mask Incident, after the fall of the CPG, the Institute spent the next 40 years doing nothing but hiding underground, staying totally out of the affairs of the people of the surface.
Despite that, the people of the surface kept thier own paranoia alive, and blamed the Institue on everything that happeend, even when it wasn't thier fault.
The Broken Mask Incident shot surface paranoia to new levels, and forced The Institute's hand into having to fuck with the surface to keep them too divided to allow them to attack The Institue.
Its actually a rather tragic story because The Institute had to become the evil the people of the surface thought they were, in roder to defend themselves against the previously baseless paranoia that they were evil.
>instead of giving the seeds to Warwick let's body snatch him then plan to kill the whole settlement once the experiment is done
Why on earth would they just GIVE Warwick the seeds, when anyone who does that would be seen as an Institute spy or w/e, and Roger would have thrown them out out of fear of
>MUH INSTITUTE!
You are acting like the people of the surface are shown as reasonable, and well adjusted, people.
They are not.
