I try not to talk too much about Satoru Iwata because of this.
He was a great man who did a lot of great things for Nintendo. Some of his decisions were questionable. I just can't blame a single man for the failings of an entire company, though.
It's out of respect, but also out of my own recognition that nothing can go perfectly. I don't think I could be a president of a company. It takes a lot of effort, sacrifice, and vision to lead an entire business successfully into the future and beyond.
If you were in the position, how would you have acted? And how would you have reacted to the market's response? It's not some simple thing. It was probably the man's entire life, despite people making so little of it.
