Weren't those fake Batmen the Joker killed civilians? Not to mention the motivation of the two villians were completely different.
1st: YOu acting like cuz the Joker didn't target civilians that he couldn't have killed any if he wanted.
2nd: The Joker chose to target the entire criminal underground and the entire law system. He wanted to create anarchy and prove the people of Gotham would survive it and become it while destroying Batman at the same time. His entire philosophy came to light cuz Batman became the villan of Gotham in the end. Yea thats some p*ssy shyt
3rd: Bane was written to be a terrorist character. Joker was written to terrorize Batman and completely break him mentally in which he had success. Bane killing innocent civilians on some terrorist shyt isn't anything to brag about.
