Throughout the Muggle friend Jacob (Dan Fogler) a wand, prompted by Dumbledore. Giving a wand to a Muggle is not only illegal but very dangerous - yet this is a minor infraction compared to the ways Dumbledore puts Harry (Daniel Radcliffe) and his friends in danger throughout the Harry Potter movies.
Most of Dumbledore's reckless actions were justified by his war against Voldemort (Ralph Fiennes), while others - like sending first-year students to detention in the Forbidden Forest - seem pointlessly dangerous. Dumbledore also plans his dangerous schemes while leaving everyone out of the loop. After Harry faces Voldemort in Harry Potter And The Sorcerer's Stone, Dumbledore tells him he is too young to understand the connection between his scar and Voldemort. And in the last movies, Dumbledore sends Harry on a quest to destroy the Horcruxes but refuses to tell the Order of the Phoenix (who could have helped) about it. Snape (Alan Rickman) summarizes this issue best when he confronts the Hogwarts heaster in The Deathly Hallows book: "I have spied for you and lied for you, put myself in mortal danger for you. Everything was supposed to be to keep Lily Potter's son safe. Now you tell me you have been raising him like a pig for slaughter."
Indeed, perhaps the worst thing Dumbledore does is groom Harry to be courageous and skilled enough to kill Voldemort, knowing he would have to die in the process (as Trelawney knew Voldemort's soul was inside Harry and created "the chosen one" prophecy in front of Dumbledore). So why does Dumbledore get away with putting Harry (and many others) in such danger? The only obvious answer would be his famous status as the most powerful wizard alive. As the greatest wizard, Dumbledore has the ability to destroy Voldemort, but not without Harry's help - his reckless actions are thus "for the greater good." But this is the same motto Dumbledore's friend-turned-foe Gellert Grindelwald (Mads Mikkelsen) used to justify his horrific actions in the 1940s global wizarding war, raising the question as to whether Dumbledore's approach is actually justifiable at all.
There is an explanation for Dumbledore and Grindelwald's common means to a different end. Grindelwald assumed this motto from a letter Dumbledore sent him in the 1890s after the two met in Godric's Hollow and formed a close relationship. Grindelwald told Dumbledore about his plans to establish a regime in which wizards ruled over Muggles, and in one of his letters to Grindelwald, Dumbledore says: "Yes, we [wizards] have been given power and, yes, that gives us the right to rule, but it also gives us responsibilities over the ruled... We seize control for the greater good." This became a justification for Grindelwald's crimes against Muggles, but it also shows Dumbledore's thinking process as he sends Harry to his (almost certain) death several times.
While many wizards around Dumbledore see his reckless tendencies (his brother Abeforth Dumbledore saying "people had a habit of getting hurt while he was carrying out his grand plans"), they often find out about his plans after he puts their wheels in motion. During the Battle of the Seven Potters, Dumbledore had Snape inform Voldemort when Harry was to be moved so Snape could cement the Dark Lord's trust in him. Dumbledore protected Harry with a plan that killed Moody (Brendan Gleeson) and Hedwig, and everyone had to let him get away with it, as only Dumbledore was powerful enough to carry out his grand plan against Voldemort to fruition.
At the end of Harry Potter, Dumbledore its to Harry that power is his weakness, which is why he never accepted a Ministry of Magic position. Harry was a pawn in Dumbledore's war against Voldemort, and people turned a blind eye to his reckless and manipulative behavior because only the greatest wizard could defeat the Dark Lord. However, while he was ultimately successful, his methods remain undeniably unscrupulous in both the original Harry Potter saga and the ongoing Fantastic Beasts series.
