Are you asking for an ethical opinion, or legal one? I am no lawyer, I have no idea if you could be on the hook for reckless endangerment. If you know that your choice is risky, and you fail to act, then there are circumstances when you could be criminally liable. But usually these are situations where the law prescribes a duty to act.

Are you comfortable endangering those around you because protecting them is an inconvenient imposition on your freedom? That's an entirely different issue.
