Of all the side part inHarry Potter , Sirius Black is unquestionably at the top of the leaning of fan - favorites . This is n’t surprising as he ’s get a tragic past , a brooding personality , and a band of unresolved issue . Also , as many rooter love the Marauders Era , there ’s a bunch of sake in knowing more about Sirius .

Sirius is overall a good character . He was amember of the Order of the Phoenixboth times it was created , and he dedicated his living to attempt to stop Voldemort from gaining power and suffer others . However , Sirius also had some fault , and he made quite a few mistakes .

Going to see how Harry off on the train

When Sirius is back at Grimmauld Place and not allowed to will , he gets agitated and ungratified . Seeing as how he hat subsist there with his bigoted category , it ’s understandable that he would be upset , and he also had already expend 13 days in Azkaban .

However , he put his own life , and the life and privacy of other decree members at endangerment by go bad to the Hogwarts Express platform .

Breaking Ron’s leg

WhenSirius escapes from Azkaban , he really only has one end . This finish is to murder Peter Pettigrew , and while Sirius is n’t ’ a scoundrel , he does quite a few things in his quest of Pettigrew that made him seem like one .

He clear was n’t totally in his right head yet after everything he bear , but the way he aggress Ron while in his Animagus form was too aggressive .

Almost murdering Pettigrew in front of the trio

Pettigrew was a horrible , worthless person who in many path deserve to yield for his crime . While Sirius ’ fad and pain make sense , he was way too intent on murdering Pettigrew in front of three 13 - year - olds . Harry was proper to discontinue him to ensure Sirius ’ freedom .

While try on to wipe out Pettigrew in that way was n’t right , Sirius and Lupin should have been smarter about keeping Pettigrew in substantiation . They should have at least set a spell on him so he could n’t get away so easily .

Being too arrogant

Sirius is overbold , well-favoured , and beguiling , and he also come from a well deal of money .

With his talent and good looks , it ’s not surprising he was rather arrogant and full of himself . While every person has their flaws , his arrogance was not a good thing , and it did lead him to look down on other masses and think he was better than them .

Aggressively breaking into Hogwarts

Just like when Sirius broke Ron ’s wooden leg , even if he did n’t mean to , Sirius was also wrong to taste to break into Hogwarts over and over . He ruined the Pink Fat Lady ’s portrait , and he then stand above Ron ’s layer with a knife in his hand .

While wanting to mutilate Pettigrew might have made some sense , he could have incidentally suffer an innocent student , and it did n’t make him look free either .

Guilt-tripping Harry for not being reckless

Sirius distinctly did manage a plenty about Harry and wanted to be a good godparent to him . While he often was a salutary wise man who look out for Harry , he also made some fault .

During Harry ’s fifth year , he guilt - trip Harry for not being more reckless under Umbridge ’s rule . This was n’t good advice as Harry ’s safety was at risk . Sirius was definitely projecting his own issues onto Harry , and it was very unfledged .

Running around the Hogwarts grounds with werewolf Lupin

The Marauders are emphatically an exciting and interesting group of friends , but they were n’t always heroic . They generally think of themselves as above the rules , and Siiurs and James were the ringleader . While turn into Animagi to help Lupin was admirable , they also did so illicitly .

Then , on top of that , they would run around while Lupin was in his loup-garou form . While , fortuitously , no one ever got injure , they were cast the lives of so many citizenry at risk .

Mistaking Harry for James

In the fifth book of the serial , it ’s clear that Sirius is starting to drop in many ways . All the trauma he has suffered is catch up to him , and he ’s dealing with depression and being stuck in a speculative environment .

So , while he clearly deserves compassion , he was wrong to project these take onto Harry . He wanted his best friend back so disadvantageously that he did n’t focalize on protecting Harry as much as he should have .

His treatment of Kreacher

One paradox about Sirius is how he treat Kreacher . While often Sirius talked about treating others well , even if they were of a scummy condition than you in company , he did n’t apply this to Kreacher .

He begrudge him because Kreacher prompt him of his family , but his cruelty and indifference really ended up make many problem . He could have tried to have some reason of Kreacher ’s hurt , too .

Trying to get Snape killed

Snape was n’t precisely an guiltless company , but the Marauders did take their intervention of Snape too far multiple times . The bad affair Sirius ever didwas to try and pull a prank on Snape that could have gotten him killed .

By telling him how to get through the Whomping Willow , he was putting Snape ’s life at peril . Not only that , but he was also frame the safety and happiness of one of his practiced friends at risk . If Lupin had hurt or killed Snape , it would have devastated him .
