Why didn't Nintendo make more realistic, violent games for the Wii just to prove 3rd parties wrong?

Nintendo doesn't often make games like the ones you described, because they don't have that specialization. But they haven't had any issue publishing mature games that were developed by third parties.

Nintendo could make a violent game any day, they just dont want to. It has nothing to do with specialization but rather the fact that thats not the image they are trying to send as a gaming compay.

Not sure it has anything to do with image. Because when the publish an M rated game it's their name that is plastered on the front of the box.

What mature games has Nintendo made for the Wii? 

They published Zangeki no Reginleiv on the Wii.

They're starting with publishing Ninja Gaiden 3: Razor's Edge on the WiiU.
