So does this mean(possibly) that there would be regret or that it would be a bad thing or could it be translated "be completely/fully dead"?
Could it also be "completely disappear" and is the どこかへ not translated just because it's awkward english?
It seems like it means to "go and do" or to "finish off" which kind of fits with the completeness in english. But it kind of seems like one of those things like "ne, wa, ze, zo" at the end of sentences that aren't really translatable. Any clarifications would help. After seeing it enough it will probably stick in my mind what situations it's used in.
