''How can you wish someone RIP or ''Rest In Peace'' when their
last moments were troubled? It's a logical fallacy.'' - a friend
asked a good question. This was my first thoughts; and perhaps
it may help you. -Ken
Well, the hope is that either a) there's an After where peace
may be found or b) it's simply over and if you define Peace as
stability, nothingness is pretty stable - hence peaceful.
Awareness of one's own peacefulness after death is another
thing.
Also, in a lot of language (we see this phenomenon in math all
of the time): There are a lot of hidden words that are
unspoken/unexpressed // much like eliminating variables in math.
They're still there, but unseen.
So *perhaps* in this case R.I.P might be thus:
''[May my troubled memories of this individual] Rest In Peace''
In other words, a wish that reflects back to the sender, helping
them cope with a difficult situation.
