A relativistic kill shot would take out a lot more of Earth's biosphere than humans are likely to. If we kill ourselves, bacteria and cockroaches will live on. Not so much, if Earth is vaporized to make way for a hyperspace bypass.

On the upside, the bypass is very splendid and worthwhile. Even ignoring something as extreme as the Dark Forest theory, it still seems like a questionable policy. A more conservative aim would be to want to maximize development time against the risk of discovery, ideally ultimately finding yourself in the role of observing without being observed. The history on our planet of first contact between disparate groups of humans should be illustrative. Even when people had good intentions, the unforeseen impacts could be enormous; I’m thinking of smallpox, and even the history of coexisting Neanderthals and Homo Sapiens. Maybe aliens are totally different, but it’s a hell of a thing do, assuming they would be more benevolent.
