Just add some context. They actually never really planned to, nor really wanted to destroy the "safe" places. They had actually different objectives and sometimes well, the results of their actions ended up destroying them.
Such as trying to rescue 2 people from a military compound (full of soldiers and machine guns, obviously).so they lured the infected to keep them "busy"
About the beautiful compound in baja, well Daniel were captured, went a bit crazy, and burned the thing to the groundwell bad luck ? lol well most of them are probably still alive
But the whole idea of the show is that there is NO such thing as a safe place, in this apocalypse. Whether it is because of the threat from the exterior because it's tempting from outsiders (for example the boat, or the fancy hotel, the Colonia) or because of the threat within (the hotel, with both the two kids, and Travis and the rule established)and also the baja and the cult around the infected and how they are perceived
Yeah I know, I think it's a bit far fetch, since I'ld like to think that NOT most of people would become murderer so easily
Don't forget : no messy things, no mean people = no drama, NO SHOW
