YES AND A THOUSAND YES!!!! READ THE MANGA.
OMG, I cannot emphasize enough how GOOD Tokyo Ghoul manga is. Don’t pick up where the anime left off. Read from the very very beginning to get the full experience. The anime condensed like 70+ chapters of the manga and a lot of stuff were lost along the way. You have to read it from the very very very beginning or you will miss out on a shitload of things. Also, keep an eye out for the little details that Ishida-sensei throws here and there. Like manga panel parallels, hidden tarot card numbers, lots and lots of symbolism and foreshadowing.
The manga ended with ch 143. GO READ IT NOW. And good luck. You’re going to need it! *evil laugh in the distance*
