unavoidable; inevitable; there's no help for it
A set phrase meaning that a situation cannot be helped or avoided; often used when resigning oneself to an outcome. Slightly formal or literary.
Now that it has come to this, there's no help for it.
The result is unavoidable.
Also means 'unavoidable', but often used in more objective or official contexts. 是非もない carries a nuance of resignation about right and wrong.
Standard kanji spelling using 是非 (right and wrong) plus もない (there is no).
Variant spelling using the kanji 無 for ない; slightly more formal or literary.
From 是非 (right and wrong, pros and cons) + も (inclusive particle) + ない (not exist). Literally 'there is no right or wrong', implying that the situation is beyond judgment and thus unavoidable.
