You just contradicted yourself. If the CEO is unwilling to start a bio-weapons division duo to lack of profits or excessive risks etc then that's a amoral decision because morality did not come into play. However, if they decide it may be profitable, but it's immoral so there not willing to go there then the company was constrained by morality.

PS: It could even go the other way where a CEO feels it's his patriotic duty to aid his government so he wants to start a bio-weapons division. The point is not the choice the point is why it was made.
