I basically agree with Gary.
5 might be grammatically ok but would be better without "the". But it sounds weird as a stand-alone sentence.
It is unfortunate that things happened this way. (good)
It is unfortunate that conditions developed this way. (correct but awkward)
The grammar of 6 is ok, but its meaning isn't clear.
A parent might say
"Haven't I raised you better than this?" when disappointed in the actions of his child.
