in the cinematic we can see that zeus needs to die in order for fear to come out. as you said, fear zeus comes out of his body. if hearts erases zeus (which he can, as zeus in his base key only has AE, which hearts can interact with), he cannot let fear come out, even if fear its imbued inside his soul
as he needs to be killed in order to do so
that is never said, Zeus "died" and fear came out since Fear is not reliant on his body, thus if he is erased, thus his body functionally "dying" fear out come out since it doesn't need his body at all
we are never told he needs to die, for all we know it happened because his body stopped functioning, also as you said, if there is no body, then there isn't anything keeping fear inside said body thus it would come out
and i repeat myself: killing someone and being erased out of existence is NOT the same. if in order to achieve X, you explicitly have to be killed in order to do so, you couldn't achieve X if you are erased from existence.
waiting statement for that still
you can't die if you don't exist no more
and to exist purely as a soul is dying, which is what will happen here even by your logic
and how do we know that zeus has to be explicitly killed in order for him to release the great evil of fear?
it's simple, if zeus doesn't have to die in order to fear to come out, then why does fear zeus come only after kratos killed him in GOW3 when the great evil of fear resided inside zeus' soul eversince kratos opened pandora's box in the first game? by your logic, he could have simply realeased his fear form at any time, has his soul (which contained the great evil of fear) was always there
.........what? when have i said he didn't need to die? obviously he can't access on his own, but that is the thing, we equally not said that the evil doesn't come out if he isn't killed, aka that it only comes out if he dies, which given the nature of what fear is makes negative sense, the thing is his soul, if the body goes away then the soul is still there to become fear
all that we see in the final fight of GoW3 is that his soul/fear got out of his body, if there is no body then........obviously there is still his soul/fear, it would just skip the part where he gets out since..........it would be open already
yet, as i explained, even though fear resides inside zeus' soul, fear zeus doesn't come out of his soul, it comes out of his body ONLY when it's deceased
it IS his soul that comes out, possessed completely by fear, why do you think something that is in his soul would need to come out of something......that isn't his soul? his soul got out of his body, which was just fear at that point
literally nowhere in the profile does it say "only killing makes him go to this form, it is a limitation"
, + he has never shown to make fear zeus appear out of nothing
........what nothing? his soul is what fear is in, his body literally matters not here
