Haha, what an awesome question. I should check these forums more often.
When I first saw the title, I actually dismissed fear first. I thought of love, then I thought "Nah, it's only
in anime that they show love as being the most powerful". In real life, I seriously don't think love is nearly
as powerful as hate or anger. Actually, I'll take a step back first. Obviously all three are powerful emotions, and
all three can greatly boost energy and determination. But realistically, I don't think love is nearly as quick to
boost those as fear or anger. Whenever I see someone saying "Love conquers all!" I just think along the lines
of "Get Real".
But to stop this from devolving into another essay like most of my useless posts, I'll just say, that though
I'd like to say I think anger is the most powerful, I would have to admit
that in the end I'm a coward more than an aggressor, so I personally think fear is the strongest. True, as someone
said, fear can make you freeze, but it's the quickest to boost your energy and determination as it only needs a
little to begin massive adrenaline rushes, and after the freeze time you go really fast.
