I had some really good steak last weekend
Was it grilled or broiled?
Grilled, we had a Memorial Day cookout
Nice!    The unofficial start of summer!
Absolutely, Steak well-done with ketchup and an ice cold beer. What could be better!
I prefer medium well and grilled to preserve the flavor of open fire
To each his own.  I worry about food borne illness, hence the meat well done
Raw meat such as steak tartare is a problem, but any cooking kills bacteria.
Even if it is pink inside? 
Yes, since meat is mainly water, protein and fat.
