This , That and All

1st Person: You did "This" because of this,  you were forced to do "that" which failed. You were not supposed to "this"  as it is wrong.
2nd Person: As a part of usual routine I did "this" . dont know why "that" failed. I asked others if "that" failed coz of them. Got no answer from them.

Now does that qualify the 2nd person from doing "this" coz nobody took the blame for the failed "that" even after the 2nd person knows that doing "this" is wrong.
