I was thinking about it and is it really luffy's fault he is bạn know .... the way he is. Just think about it for a second...

he grew up with shanks ( his hero) and his crew and piarates tình yêu to have partys and drinking... not the ideal envorment for a kid.. ( but thank bạn shanks for giving Luffy his dream!)

About Garp... throwing your grandchild into bottomless pits and jungles in the middle of the night isnt what i call a "stable" envorment" Garp was training Luffy and Ace (maybe sabo but probably not) how to marines kinda turned into 'piratate' training. For example Garp had a flash back...
