I want to say "His life has been set on a different course since then." but push it into the past.
I can come up with two options:
- His life had been set on a different course since then.
- His life was set on a different course since then[ever since].
Between the two, I am thinking the simple past form is the (more) right one, but do you see any issues with this (also, is this a common form of expression)? Normally, 'since' is used when there are two temporal points that mark a certain interval... but the latter temporal point is unknown, or it is more implicit than normal (also in relation, 'since' is normally used with the past/present perfect forms, so this is an aspect that causes me some confusion). The default assumption would be that he followed this different life course until his death, especially when 'ever since' is used. I would appreciate your input/thoughts on this.
