Technically you might be able to make that claim, but I have a hard time understanding the point if it saves more people than it kills. Then at least morally I would question who is really in the right here.

I'll give you a hint: it's not the company that lied about whether their product kills people and paid others billions to do it as well.

Exxon could've just been honest and oil would still have been sold and used and saved people, we could've just been using it more responsibly.

But they lied, for profit.

Why are you hung up on a binary view of this? Do you think our current usage of oil is responsible?

Do you think a corporation encouraging extensive oil use at all cost is the same thing as "oil saves lives?"

It's not.

I think our current usage of oil is responsible yes and I think it's irresponsible to not use oil.

There are no realistic alternatives to 99% of our current use of oil which includes more or less any product used in a modern civilization so unless you can point me to some alternatives I think you are the one who has the immoral position.
