No one is responsible for unpreparedness on a mountain except for the hiker (or party they are with).  Condolences to the family, but it would appear the wrong decision was made and this individual paid for it with his life. 

Anyone who has properly researched this mountain knows that there is one way up and one way down. We can't blame others for potential ignorace. 

I'm making a lot of assumptions here, and I don't mean to debase the loss of a life. But the responsibility falls on the hiker themselves, not some article promoting 14ers.
