I'm inclined to say that if there's a bug in some grading software and some students kill themselves for failing, the problem here is not with the software.
That’s like saying that if there’s a bug in some missile targeting software and some some students die from playing in the park, the problem is the park that they chose to play in.
Wouldn't be the fault of the organization that fired the missile? Especially if they were told ahead of time "This missile's targeting system is only accurate 99.9% of the time so do be careful"
Working hard for good grades and being disappointed at failure is normal too.
Software design could, probably should, have incorporated the social context of failure. This is Asia, India in particular, that we are talking about here - the hyper-competitiveness that these kids go through is probably worse than what medical doctors go through in prestigious schools in the US.
