Yes, Luffy's past has sad elements, primarily the perceived loss of his brother Sabo and the traumatic death of Ace at Marineford, but compared to most Straw Hat crewmates, his childhood was relatively happy due to mentors like Shanks and Dadan, making his sadness more about profound loss and responsibility rather than relentless suffering.
To be honest, Luffy didn't have a sad life. He had Shanks and then Sabo and Ace. His life wasn't sad but hard because of Garp, the loss of Sabo and then Ace but he had his crew and his brother, Sabo was actually alive. Also he received some hard pain by being hurt with nailed gauntlets as an 6 years old by Porchemy.
Set aside Nami, Sanji, and Robin's backstories — Kuma's life is the most heartbreaking story in all of One Piece.

In Inuyasha, it's revealed that Sesshoumaru never sheds tears, no matter what. Jaken explains that if a situation warrents tears being shed, he will cry on Sesshoumaru's behalf. Erza of Fairy Tail plays with this; she cannot cry in her right eye, even when it was healed of damage from when she was a slave.
Zoro, Chopper, Franky, Brook, and Jinbe.
The "D." in One Piece (like in Monkey D. Luffy) is a mysterious inherited initial for a secret lineage, the "Clan of D.," who are considered "Natural Enemies of God" (the Celestial Dragons) and destined to cause significant world changes, often associated with bringing smiles, freedom, and pursuing dreams, though its exact word meaning remains unknown and heavily theorized as Dawn, Dream, Democracy, or Devil.
By the time Zoro was 8 years old, his father had already been killed in a battle against pirates threatening Shimotsuki Village, and his mother had died of illness, leaving Zoro orphaned. At the village's dojo, he trained to be a swordsman.
While opinions vary, Portgas D. Ace's death is widely considered the saddest in One Piece, primarily because he died protecting his brother Luffy, fulfilling his desire to be loved, but at the cost of his own life during the Marineford War, devastating Luffy and fans alike. Other frequently mentioned heartbreaking deaths include Belle-mère (sacrificing herself for Nami and Nojiko), Donquixote Rocinante (Corazon, for Law), Whitebeard (a legendary figure falling), and Pedro (a selfless sacrifice).
Season 6, Episode 325: Goodbye, Merry | Luffy Cried
The ship had been with them for a long time and had become a member of the crew. As the ship sinks into the sea, Luffy breaks down in tears, unable to control his emotions. This episode is a testament to the bond that the crew shared with their ship and each other.
Lacuba is a prideful man, as he would rather attempt suicide than spend the rest of his life being humiliated as a slave.
Luffy is just a kid, he a boy not asexual.
Several One Piece characters have romantic feelings for Luffy, most notably Boa Hancock, who is openly obsessed and wants to marry him, and Alvida, who fell for him after he defeated her. Other characters with strong affections include Nefertari Vivi, Rebecca, Shirahoshi, Marguerite, and Carrot, though Luffy generally views them as friends and is oblivious to most romantic advances.
Luffy was traumatized and lost consciousness when Ace died because, despite his best efforts, he felt weak and unable to prevent it.
Luffy is the complete name, but first and second name are inverted like they do in Japan. So, written in the western way would be Luffy Monkey D. or D.
In the same vein is an unusual behavior that seems to be common to "D." – they are often seen laughing or smiling right before they die (or think they are about to die), as though they have accepted their fate and exhibit no fear of death.
Language includes profanity ("ass," "s--t," "damn") and insulting name-calling ("sniveling runt," "scum," "s--thead"). A character gives someone the middle finger.
also in impel down, ivankov shortened luffy's life by 10 years. Hopefully Law use his Devil Fruit to Luffy to become immortal According to Doflamingo, the Ope Ope no Mi has the ability to grant eternal youth. However, it comes at the cost of the current user's life.
All the straw hats have suffered a lot, but I think none like Brook. Not only was he the last of his companions to die, but he also had to arrange their corpses when he woke up. He had to spend 50 years alone, accepting the fact that he was just a skeleton, in the shadows.
Even after the two-year timeskip, Hancock continues to be in love with Luffy as much as before despite that the latter openly rejected a wedding proposal from her.
