Are these sentences correct:
1-He wasn't a real friend, not helping me when it was so easy for him to do so.
2-He wasn't a real friend, not standing by, watching me get beaten up without lifting a finger.
They have the same structure and yet the clause functions differently in them. In 1 he does not help me and in 2 he does stand by and watch me get beaten up.
I think both are correct but when they are read the intonation is different.
