I didn't say the consequences should be proportional, I said the responsibility (or blame); and profits derived should just be one part of the equation.

Criminal consequences of a company collectively being responsible for the deaths of individual(s) shouldn't just disappear because no one individual ostensibly caused it. A company is a system of incentives and processes, and if those incentives and processes are leading to preventable deaths and suffering, those who benefit most from and are most responsible for perpetuating those incentives and processes should be held liable.
