undo him to give back

hola, me gustaría que alguien me ayudara con el sgnificado de la siguiente frase: "he was incapable of nursing an evil thought which it would undo him to give back".

Gracias y saludos.:)

¿Puede revisar la oración original? Así no tiene sentido.

sí es verdad. Sé me pasó. es la siguiente:

"he was incapable of nursing an injustice which would cost him good living to repay, an evil thought which it would undo him to give back, or even sorrow in his bosom".

gracias.

Maybe context would help, but it's odd English. Something seems off. The word "it" should be deleted from the phrase "an evil thought which it would undo him to give back" but I still don't know what it means.

repaying injustice, giving back an evil thought---strange

I could see something costing "a good living" if, for example, someone would lose his/her job but "cost good living" doesn't sound right.

What is the source?

marialec,
it´s from a book "The man who loved children" written by christina stein.
and yes, it´s odd English.

Thanks for your interest and help.

La autora es inglesa o norteamericana? Porque ese apellido me suena aleman... Quiza estas leyendo una traduccion del original que no es muy buena, y tradujeron mal esa frase... Se que no es de mucha ayuda jaja! Pero quiza podes buscar otra edicion, a ver si esta igual... :D

The Man Who Loved Children by Christina Stead

Ohhhhhhhhhhh.... Ok, nevermind! :p
