Forge can crash during installation due to various factors, such as the use of an incompatible version of Java, a corrupted or incomplete download, or conflicting mods.

Forge goes way beyond that, however, by allowing users to overwrite the Java building blocks (ha) of the game. You can literally change Minecraft into a different game.
