why “End Do Not Justify The Means”, CRIMINALS' EXCUSE

The proverb “Ends justify the means” had been a subject of long debate for past few decades, let me explain this by giving an example, Abortion to save a mother. In this case doctor’s end goal is noble. Therefor ends justify the means sometime.
This proverb is said by Niccole Machiavelli, which means that, any method (mean) even bad is also allowed for achieving an end, especially good end. Niccole Machiavelli expression focuses on end.
But some warmongers, politicians and criminals had misinterpreted it for their economic gains. Adopted tyrant means which led to dreadful conditions.
Thus this proverb was used as an excuse by many people in order to justify their crime. But a good end cannot always justify bad means. Because, for an end to achieve, there are multiple means. And it depends on an individual that weather he/she adopts ethical means or not therefore end do not justify the mean i.e. use of wrong mean by Hitler, cheating in exam etc. . However end justifies the mean only and only if both the means adopted and end is good. Beside this, there are some special cases in which end justifies even bad means i.e. testing of vaccine involuntary.

This proverb “end justify the means” has had been used by criminals to justify their crimes. They argue that their end goal is good i.e. economic gain. Criminal uses this proverb to justify their organized crimes regardless of its bad consequences. For example, drug trafficking can earn you money, but at the same time drugs are damaging the life of thousands of people. Thus this bad mean cannot justify their good end.

Nowadays many countries using unsustainable means for production in industries. Fo example, coal use as a fuel but in contrast coal on burning emits carbon into air, as a result global warming rises. So due to the use of these unsustainable means global warming had affected people by heat wave

, floods. Although their end goal is to left their economies, which is good. But there means had severely affected the world. Thus bad means cannot justify good end.
NOW IT IS UPTO YOU TO DECIDE THAT WHETHER END JUSTIFY MEANS OR DO NOT ?
