What is the significance of the phrase "the end justifies the means" in ethical decision-making?

The phrase "the end justifies the means" suggests that achieving a positive outcome is more important than the methods used to achieve it. In ethical decision-making, this idea raises questions about whether it is acceptable to use unethical or harmful actions to achieve a desired result. It challenges individuals to consider the morality of their actions and whether the consequences justify the means used to achieve them.
