Carriers

so i was watching the movie Carriers it was about a contagious disease that doesnt have a antidote or something the movie was really sad.. its like leaving your love ones alone so you can survive.. it was like the saying of the vampires (in vampire movies) "what is forever if you will spend it alone?".. i mean if there isnt anything left in this world why on earth i would kill or leave the ones i love so live an empty life.. what is there to live for? so you can live alone and empty.. IMO i'd rather die with the one i love rather to live my life alone and miserable.. am just saying...
