idk what to put as the background so i just used a world map

You and me both!

not to mention my history teachers throughout high school have all been amazing and instilled me with argumentative skills and knowledge of history

History is always open to interpretation though, unless you’re only sticking to numbers (and even they are subject to creative accounting. As a small example, in my country there is a big emphasis on lowering the “Easter road toll”. But when someone is in a car crash over Easter, but doesn’t die until after Easter, it’s not counted in the toll).
There are always debates in History, and there is often just a consensus over events (particularly their causes). Suggest you discuss this with your teachers too.

Stalin was good yes or no

This comes down to personal beliefs. If you support Stalins polices of rapid industrialization and expansion of the Soviet sphere then he was good. However since I don't agree with the famine and purges he caused and he was anti usa and a communist, I believe he was bad.
