WARNING: The following contains major spoilers for Strange Academy #14, on sale now from Marvel Comics.
Although the students of Strange Academy are no ordinary teenagers, they still have much to learn about mysticism and alternate dimensions. As they take a trip to the X-Men's darkest timeline, the students have no problem with expressing their thoughts on the world, with one of their opinions shedding an whole new light on the dystopian reality created as a result of the Age of Apocalypse.
While no day at school in Doctor Strange's New Orleans academy is ordinary, the world in which the students find themselves during their latest outing is unlike any they could have expected to visit. In Strange Academy #14 (by Skottie Young, Humberto Ramos, Edgar Delgado, and VC's Clayton Cowles), Brother Voodoo has taken the class all the way to the Age of Apocalypse where the battles between mutant kind and their would-be oppressors are still being fought. They don't stay long, but the students witness enough to understand how impactful one change to the timeline can be. Powerful student Emily Bright is outraged, not only by the existence of the world but because of how it was created, and feels that the X-Men had no right to manipulate reality to serve their ends at the detriment of everyone else in the world they changed.
The Age of Apocalypse was created when Professor Charles Xavier's son Legion traveled back in time to assassinate Magneto before his actions could lead to widespread anti-mutant hysteria. Instead, Legion accidentally killed his father, with the death of Xavier leading to the early rise of Apocalypse and the decimation of Earth.
While it was Legion's manipulation of the timeline which caused the Age of Apocalypse, subsequent attempts to "correct" it by various heroes over the years have not only failed, but in many cases made the situation even worse. Many of the treks taken by the heroes of the primary Marvel Universe to their devastated counterpart have ended in further death and destruction than there would have been if they had stayed away.
Even though Emily Bright's conclusion about the inherent hypocrisy that led to the creation of the Age of Apocalypse is surprising, Doctor Voodoo's response to her observation is even more so. Rather than deflect or launch into some sort of rousing monologue as other teacher's at the school might do, Voodoo instead chooses to acknowledge that Emily is very much on the right track when it comes to her concerns.
Giving his students the room to make their own informed opinions regarding time travel rather than give them a rigid set of boundaries to stay within isn't just allowing them to form more organic views on the matter, but it also lets them know that their questions and concerns are very valid. In his own way, Voodoo is encouraging his already opinionated students to think for themselves, and is molding them into responsible heroes for the next generation.
