I want something badass. Fantasy setting, a band of brothers trying to defeat some evil. No safe characters, no animu stuff, but I do want emotional scenes and relationships
Gundam? It meets the bolded requirements but it's semi-hard sci-fi and can have anime stuff.
For fantasy you could watch Record of the Lodoss War, but it's not going to meet all those requirements. It's like Fire Emblem but more mature.
The Vision of Escaflowne is really good fantasy like you want, but it's got a tooooon of animu. It has the original catgirl.
If you want something like Song of Ice & Fire but not as good and just as unfinished you could watch 12 Kingdoms.
Actually Berserk meets all those but it's the opposite of "no one is safe" because everyone who isn't the main cast always dies and the main cast is always safe.
