Bro, killing off characters gives life to the story!
Example; I killed off #1 because he tried to interfere with 2#'s plans on ascending to demi-god rank, so 2# killed him in the most brutal way because nobody knew how much it took to kill their species.
But.. I loved #1 too much to just leave him dead, he didn't get any development either, it was in the very beginning of everything. So I created a dimension for him to be a demi-god in, a heaven-hell combo, because he was the very first death in that universe so it made sense.
Another example, #2 also ruined his relationship with the mother to his children, so #3 left home and became fallen(think lucifer but not really). As years goes on, #3 loses herself more and more due to memory loss and being emotionless, which is effects of being fallen. So she's technically dead but not really.
Now, with that being said. Phone-call seems too trope-y and cliche.
Phone: hey, so uh, this is hospital
Person: ya?
Phone: your wifes dead
Person: oh poop
It's hard to write their emotions that way, you can only really write slightly. But if the person was there to hold his wife's hand as she died, that would make a hell lot more to write about! To drag people into reading it.

"Sir.. I'm sorry."
"Shut the hell up!" Jason shouted, bringing the lifeless hand to his face, kissing it, expecting his wife to magically come back to life. They wouldn't dare to give him that same old 'we did everything we could' crap. They wouldn't. He should have taken her to different hospital, this was the most closest one at middle of night.
"But, we did everything we could-"
Jason stood up abruptly, knocking the chair back, clattering on the floor. His hands slammed the bed angrily, causing no noise. "Yes, /but/ you could've done more! I'm willing to throw all my money at you to keep her alive. I don't care if we're poor, I would've took out a loan and worked my ass off to pay it off!"
"Sir, please calm down-"
"Don't give me that bullshit!" Jason vaulted over the bed, over his dead wife to slam the doctor against the wall. "Don't call the security on me, or you'll regret it!"
The fearful, wide eyed look on doctor's face made him realize his actions, what he had done. He let the poor man go, carding his hand through his brown hair, lowering his head.
"I'm sorry." He felt a hand clap on his shoulder, squeezing comfortingly.
"Mr. Farrett, it's quite alright. Emotions is a force to be reckoned with. Deaths are always the hardest concept to accept."
Jason nodded, wiping his teary eyes. He knew his wife would hate to see him blow his fuse like this. In front of her corpse, no less. He returned to her side, kissing her forehead.
"Emily, I'm sorry. I didn't mean to." He whispered, brushing her blonde hair aside, staring at her lifeless, but beautiful face.
(Wrote more than I'd intended, heh)
