Taking someone a long time to do something or make something happen.

- Sun Tzu

Just like the movie “The dark knight rises”

But instead you need to give people the L if not one day you will be on the receiving end of it

Coined in the movie "The Dark Knight Rises" by Harvey Dent, A.k.a. Two-Face.

It is the philisophical summary that, no matter what good you intend to do, as long as you live and continue, you will bring about just as much evil as good, if not more through accident or intent. Death becomes a saving grace, providing vindication for their actions and preventing a worsening of certain outcomes through inactivity.

When you only try to see good in people, always help others, be everyone’s favourite, and suddenly die somehow, vut everyone remembers you as a Hero. Or you have lived enough to see how the world really works, you’ve seen a lot of times that you can’t trust anyone, people use people who have a good heart. You need to be heartless to survive in this world. The ‘Hero’ would be eaten alive by this world if they still lived. They would have been a doormat to everyone.

A quote from Christopher Nolan's The Dark Knight by the character Harvey Dent in reference to Julius Caesar and Batman. Repeated by Batman at the end of the film.

There are several possible meanings:

1. Absolute power eventually corrupts (as in the case of Julius Caesar).
2. Being consistently heroic is difficult if not impossible, circumstances will eventually push you towards villainy (as in the case of Harvey Dent and Batman).
3. Public opinion can easily change and will eventually change. Many people have the tendency find faults even when there are none. It can also be easily manipulated. You might adhere to your code despite 1. and 2., you can still be painted as a villain by your enemies (as in the case of what Joker did to Batman).
4. Villainy and Heroism are relative and not absolute. "Good" will change with time. Different people have different concepts of "good" (the actions of Julius Caesar can be judged very differently by different people throughout the different ages). In many situations, the line between the two concepts can be very blurry (following the law versus vigilantism).

When someone lives a great life and helps others, hence is a hero, however as time passes they are corrupted for whatever reason, and live long enough to become the villain. This change is inevitable for most heroes, unless they take the opportunity to die a hero earlier (or quit the business of being a hero, as its suggested bruce wayne was trying to in the dark knight rises' end)

Quote by Harvey Dent in Batman The Dark Knight

This is quoted from Two-Face of the Dark Knight movie.An interpretation of this quote is that you could stick to your morals,of what's right,to be loyal to a cause,even if it is of your detriment (die and be a hero).Should you contradict your values for your betterment,you may find yourself making the same decisions of the very people you yourself considered corrupt/evil(live long enough to see yourself become a villain.)

Black Mirror(15 million merits)
Before:Main character opposes system of the rich profiting off of working class

After:Main character is hired by rich to host a vlog to rant about systemic oppression,only to be benefiting from the system he once fought against

It means that in life you are given choices and this defines who you will become morally. You choose who you are and if you choose to be bad than you are the villian but if you choose to be good then you are a hero. We are all faced with the choice of being good or bad but you only you can choose it.
