If you took the chart as an indicator of objective morality, then yes it invalidates it. But that's not what the chart is about. The title clearly indicates that it's a subjective assessment of people's views.

So Canada ranks as "good," somewhat because Canadian people are generally decent, but moreso because there's a common assumption among Canadians that other Canadians are generally decent.

Likewise in India, the chart indicates that among Indians there's a common conception that Indians are generally morally decent. This subjective perception is obviously layered with cultural interpretations of what constitutes morality.

The actual, objective morality (if such a thing exists) doesn't factor into it as much as those cultural factors.

There's also the selection bias to account for. Indian society is far more stratified than Canadian society. Who exactly is responding to the survey, and are they only considering members of their own caste in their response?

It invalidates it as a tool to judge the morality and ethics. The chart might still be useful to show how heated cultural and political climates are in each state.
