I wouldn't Judge Cat-egorically that to be correct.
Is Én Pasant really cheating?

it IS!!!! its BRILLIIANT, FANTASTIC, AMAZING!!!! (only when i use it, not if my opponent eats my pawn with it)

That's a good question but I think everyone is used to en passant so games would be much different in all stages.

The real origin of En passant, is that the creators knew it would be hard to capture a pawn when it gets to far, so they added en passant to prevent that. It is very rare, but it does exist.

Yep!

Nope.
Anyone that doesn't know why en passant exists does not know the history of chess. It was added soon after the "pawns can move 2 squares" rule. The reason is inherently obvious, and necessary once you add the 2 square move...to keep people from getting a passed pawn merely by jumping 2 squares right past an opponent's pawn. This is why you can only play en passant on the move directly after your opponent moves their pawn 2 squares, not 5 moves later on.
So, rather than making the game more complex (the 2 square pawn move did that ...), it actually was implemented to keep the game simpler and more consistent. Lots of people cannot remember the particulars of en passant, but if you know the history of why it was added, it's easy to remember how it works and why.
it was to remove no proggress moves
