After thinking about this question in depth after already giving an answer ..

I wrote all the reasons I could come up with on a list and came up with 15 .. then trying to decide which were the most important in my eyes !!

Number one ended up being to protect my wife then myself
next would be to protect my kids and grand kids when they
are with me !!

Those to me are the most important reasons I carry in
todays world of the unknown .. There are others where
circumstances might warrant intervention but that would
be on a case by case basis ..

When I first started to carry when Illinois got Conceal
Carry License my wife was unsure of me carrying as it
was so different then what had been the law before ..
Almost to the point of not wanting me too .. Over the
past couple of years she has flipped her reasoning 100%
and now asks if I have Old Betsy with me ..or one of my
other pistols .. She has never told me how she came up
with the name of " Old Betsy "for my Beretta ..

She doesn't feel safe with out it with me .. and she is
much more understanding of Situational Awareness !!
