Yes they can be mortal sins if they are acted upon. Sometimes thinking about them is acting upon them and therefore mortal. Other times having the thought and immediately pushing it from your mind using a Hail Mary or other prayer is venial because you did not entertain it yet having the initial thought was natural - that is why it is original sin. This is just my take on the difference - I can be wrong - if someone has a better take on it - please throw it out.
