no call

Kazuo Ishiguro氏のThe Buried Giantを読んでいます。
'Mistress, I beg you, allow my husband to assist with your rabbit. There's no call to spill blood in a place such as this, and no basin to catch it. You'll bring bad luck not only to this honest boatman but to yourself and all other travellers who stray in here seeking shelter. Put that knife away and slughter the creature gently elsewhere.
