Translation of "fanatic" into Estonian

So this is either a fanatic for a cause or someone who has nothing to live for.

Ta kas usub millessegi fanaatiliselt või tal pole millegi nimel elada.

With my brother dead, and we rule, we'll be better off without these fanatics.

Kui mu vend on surnud, on parem ka neist fanaatikutest lahti saada.
