When gaming on 'autopilot', all kinds of bedlam mannered madness is possible. I guess for some people, wiping out an entire population in a terminator automaton style, is just one of those possibilities.
Funny little anecdote Kyrvias. Stay awhile, stay forever eh?
For me, one rather silly roleplaying decision I made was to merge my real life attachment to caffeine intense energy drinks like V and Redbull, into my Khajiit Monk, expressed in his fierce addiction to Skooma and Moon Sugar. I was gutted to learn that you couldn't make it in the game.
I'd steal it as often as I could and hoard it back to my storage space in Ahnassi's place in Pelgiad.
This perilous merging resulted in some extremely late nights, going to bed ocassionally at dawn etc.
Situation wise, I can't think of anything overly stupid at the moment other than the usual bouts of non-thought out tactics when outnumbered.
In my early level phase, I experimented with the khajiit unarmed attacks, often charging in gung-ho jumping up down thinking I was so cat like and dextrous) slashing all over the place. Didn't take too many deaths before I realised that wasn't the right idea.
Learing to refine tactics in the game was always good fun, often with lessons well learnt.
