Morality does not say how much morality for each option

Each option where?

The first three options give you 50 Morality. The last option gives you either 30 or 70 Morality.

It's not like Obligation or Duty, where you increase Obligation or lower Duty to get the benefit. If you want to be on the cusp of the dark side or light side you give up the other options. So you don't "give up" Morality for any option.

Page 34 says a player can " choose to modify their [character's] starting Morality or gain additional experience points or credits… ". Note that is says modify or gain stuff, not modify to gain stuff.
