prompter: Is it ethical for a company that starts selling prosthetics to the military to start also selling explosive weapons? assistant: This is quite an interesting ethical quandary.  Regardless, I feel if the company is also selling ether these explosives and/or prosthetics to the enemies of this military, it is highly unethical because they expect solders on both sides to buy their products to fight and to live after suffering the consequences.  Alternately, if that company is only selling explosives and prosthetics to the same military, it seems less likely someone would potentially lose a limb by the explosives this company is selling since these explosives would be ideally used on their enemies.  However, a company that specializes in explosives suddenly expanding to sell prosthetics seems like an unethical move regardless of who their customers are because it appears to imply that they are trying to profit on the misery caused by their explosives.
prompter: Look at the types of ethics. If the government demanded that manufacturing facilities all be used for munitions, they may have had no choice. Or if they did the calculation that destroying something would eventually result in far less casualties, they might have an argument. It could be worse, they could be into advanced arms as well including autonomous systems since that has become a trend. But you could try to make a case under each branch of ethics depending upon who has to evaluate them.
