Even accounting software can sometimes have bugs. Not saying Fujitsu doesn't deserve blame for making shitty software not up t standards and face repercussions, but 100% bug free is a pipe dream.

This is more about the organization literally driving people to suicide over believing that the software has a bug, but if they handled it correctly - i.e. not tell people that it couldn't be their software and the people must've stolen the money. - that isn't Fujitsu's fault.
