Expresses the idea of a death that is pointless, wasted, or without achieving its intended purpose. Japanese has several nuanced expressions depending on whether the death is futile, unavenged, or a sacrifice that didn't pay off.
To say someone died without achieving anything, or that their death was meaningless.
Literally 'dog's death', meaning a death that is utterly pointless or wasted. Often used when someone dies without honor or for no good reason.
彼の死は犬死にだった。
His death was a dog's death (he died in vain).
こんなところで犬死にするわけにはいかない。
I can't die in vain in a place like this.
Literally 'wasteful death'. A straightforward way to say someone died in vain, without achieving anything. Slightly more formal than 犬死に.

His sacrifice was not a death in vain.
無駄死にを避けるために撤退した。
We retreated to avoid dying in vain.
Literally 'failed death', implying a death that didn't accomplish its purpose or was a waste. Can also mean 'narrowly escaping death', but in context of dying in vain it emphasizes the futility.
あんな作戦では死に損ないだ。
With that kind of plan, it would be dying in vain.
To express that someone died before they could get revenge, or that their death went unavenged.
Literally 'death of regret/chagrin'. Conveys dying with unfulfilled desires, often used when someone dies before achieving revenge or a cherished goal.
彼は無念の死を遂げた。
He died a regretful death (with his revenge unfulfilled).
Literally 'to die without taking revenge'. A direct way to say someone died before avenging a wrong.
彼は仇を討たずに死んだ。
He died without avenging his enemy (he died in vain).
To describe a death that was meant to be a sacrifice but ultimately achieved nothing.
Literally 'sacrifice becomes wasted'. Used when someone's death or sacrifice ends up being in vain.

We must make sure his sacrifice is not in vain.
Literally 'to waste a death'. Often used when someone's death is rendered meaningless by subsequent events.
彼の死を無駄にしてはいけない。
We must not let his death be in vain.
Casual ways to say someone died for no good reason.
Literally 'as if I'd die (in vain)!'. A defiant phrase meaning 'I won't die in vain' or 'I refuse to die for nothing'. Used in dramatic or emotional speech.
こんなところで死んでたまるか！
I'm not going to die in vain in a place like this!
犬死に is more colloquial and carries a stronger emotional charge, often implying a dishonorable or pathetic death. 無駄死に is more neutral and can be used in both casual and formal contexts to describe a wasteful death.
犬死にだけはしたくない。
I just don't want to die a dog's death.
無駄死にを避けるべきだ。
We should avoid dying in vain.
Avoid directly translating 'dying in vain' as 死ぬのは無駄だ or similar. While understandable, it sounds unnatural. Use the established phrases like 犬死に or 無駄死に instead.
