I really should use a throwaway account, but no one really knows about or checks this particular one (or if anyone reads this, will either disregard it as ostentatious circumstance, or anecdotal nonsense.)

Plausible deniability is fantastic.

As to avoid lurid details, I will simply say 'self defense', but admittedly more situationally capricious than particularly courageous.

The altercation lasted seconds, and I somehow maintained some amount of equanimity throughout the ordeal. As it turns out, the human neck / skull is surprisingly fragile. You would think such an ubiquitous trait wouldn't be so ridiculously common.

Considering who it was though, and their current activity leading up to the incident, my amount of guilt is infinitesimal (and this is coming from a self-destructive individual with a guilt complex).

If it wasn't me, it would have been someone else eventually. While I don't excuse my particular decisions taken, I firmly believe that some people simply cannot be helped...
