Doing wrong things to get right result
Have you seen any or all of the Avengers films that concluded with the Infinity War films? Thanos, the ultimate villain, determined that the universe's population was too high and that by eradicating half of the universe's inhabitants, a better balance would be restored for the remaining inhabitants. Thus, after acquiring all of the infinity stones, he decimated half of the universe's population. In his mind, he had done something good. The ends (a more balanced population) justified the means (killing half of the population).
Is the means justifiable in light of the ends?
If you wrote, "Does the means justify the ends?" on purpose, The answer is straightforward. Always affirmative. A person who commits an act does so with the intent of achieving a goal. They are justifying the means by committing it.
In other words, if they seek an evil means to accomplish an evil end, they do not intend to justify their actions. They do not require a justification for their actions if they seek good means for the sake of doing something good.
If you intended to write, "Does the end justify the means?"
No. This is a logical fallacy based on the concept of the "greater good."
All that matters in determining morality is the current act. Whether we admit it or not, acting for the "greater good" or "the ends" always conceals a selfish motive. An individual cannot act for the "greater good" because they are incapable of making decisions on behalf of a "greater" number of people. They can only make their own choices.
If the ends do not justify the means, they are not justified. By using immoral means, you have negated the entire reason you sought moral ends in the first place.
Few of us would accept genocide on that scale as a positive. We currently follow a set of laws, regardless of where we live or what religion we practice or do not practice, that make it abundantly clear that killing even one person is objectively wrong. While there are provisions that excuse the killing of one or more, it is still objectively wrong. Self-defense is one such instance. The laws essentially say, "It is wrong to kill, but you had no choice, and thus we will not punish you."
Thus, our society holds that the ends do not justify the means, even though some individuals (including some in positions of great power) believe they can justify their wrongdoing by claiming the benefits of the results.
