No. For a single human being to unilaterally decide to destroy an entire species would be not only abhorrent but dangerous.
Arguably, if any other species recognized afterward that human beings granted authority and agency to individuals capable of such things, that species would be fully justified in committing genocide against humanity and wiping us out to the last man, woman and child - for their own protection against us.
They might do that but then they would be wrong, as the Federation and humanity are not homogenous, like the Borg.
The great thing about debating this sort of thing is that we know how each and every Borg is meant to act. It's a given that its hive mind will tell it to assimilate.
The thing is it's only fiction, even if we had a "KILL ALL TERRORISTS" button in real life it would be to dangerous (as in difficult to define the paprameters of 'terrorist') to use.
