> that's not murder?

Well, that depends on the legal definition of murder where you live.

In lots of places, intent matters. You said the pill was added with the intent to make more money. If there was no intent to kill, then in lots of places that isn't murder but might be some other kind of criminal homicide.

For example, people at Ford made the decision to sell the Pinto with a dangerous defect to make more money and people died as a direct consequence of that product decision. The people who made that decision were not charged with murder (or anything as far as I recall).
