I don't know how to interpret this line 死んだと知らさせるより受け入れがたいから


I don't understand very well what a character wants to say...For context, this
character is on the verge of dying, he was cursed and had only a day to live
and tries to find the one who cursed him.  
While searching, he gets a phone call from a friend but doesn't answer because
they don't want the friends to worry, for they don't know that he got cursed.  

Character's inner thoughts: 悪いな…心配かけて。でもごめん…あと何時間で死ぬ…なんて。
**死んだと知らさせるより受け入れがたいから…**  

I'm having trouble with that line I bolded, because even though I broke it
down, I don't think I'm interpreting it well.  
 **" Because it's more unacceptable than telling them I'm dead".**  
I don't think this this sounds right, what is he trying to say? That he'd
rather have the friends believe he died instead of actually telling them that
is about to die so that they won't get worried?  
Is my interpretation of the line somewhat good?  
Thank you in advance for those who could help me out with it!




Without grammar analysis, close to my original interpretation in the comment,
the fact that he is going to die due to the curse is more unacceptable than
letting his friend know he is going to die and make them feel lament about him
since he has been struggling to seek one who cursed him to die to the last.

That is to say, the defeat by him is more unbearable than his going to die, so
no one wants to know he is going to lose by the enemy. I hope this
interpretation matches the plot and the protagonist’s behavior.

At this point, the 知らせる to 知らされる conversion does not change my interpretation.
