[suicide squad] Why does Katana keep using that sword??

Why does Katana keep filling her ...katana (-____-) with the souls of assholes if her husband's spirit is still in there? 

I can't help but imagine an ever swelling sea of villains and the souls of damned gotham(s? gothianian?) smashed up against her beloved. Like, wouldn't you want to kill a couple of his friends and then* put the sword on the shelf? Seems like a shitty thing to do to a man's soul...

I expect that physical space isn't a concern. It's probably a lot like Superman's Phantom Zone. Still, while she may be trying to bring her husband back, IIRC, their relationship wasn't all that wonderful either.
