Does it look better on graduate school applications if I'm getting a M.S.?
I'd have to sacrifice some courses outside of math (like english, history, etc.) in order to take more graduate math classes (need 8 total).

In general more math or related courses instead of non-related courses would support your application better. For some context, these mandated non-degree courses are not globally agreed to be necessary. For example a 4-year math degree in US can have less content in math then a 3-year math degree in Germany. Essentially some degree programs can have &quot;bloat&quot; approximating around or above of 1 year work (8 to 12 courses). It is not at all obvious that these courses in necessary (as they are not mandated in a lot of places) and I have never ever seen any admission body / personal being even remotely interested in the existence or non-existence of a -very basic introductory to a discipline of humanities-.
