It seems like the tailed beasts are getting soft but they arent. We are just finally getting to see the human side to them. Theyre inner characte and personalities. The fact that they are more than just demons and monsters and war machines but in fact have emotions feelings personalities and names just makes us see them less beastly and more humane.
The fact they have names symbolizes that they are not dumb crazed monsters and should be treated as such but should be respected. They hate humans cuz they have been treated with cruelty. Naruto with his talk no jutsu and "i can relate no jutsu" will change em as he does with all characters who were once mad at society (gaara, neji, nagato etc).
Btw we dont know hachibi name yet so dont go around saying its yamato no orochi. The yamato no orochi in japan mythology n shinto religion was an 8 tailed and 8 headed snake. This creature is not hachibi. Hachibi is an ushi oni, a demon half bull/spider or half bull/octopus. Instead kishi used this creature to be orochimarus true form or final transformation agaisnt itachi. In myth yamato no orochi was killed by the god sasunoo while using the sword (forget name). Its cool cuz kishi made itachi to slay (seal) orochimaru with his saunoo and sword.
We dont know any other tailed beast names except son goku, kurama and i think the 1 tails too. Isnt it tanuki or shukaku?! Idk or maye 1 tailed is not named yet
