I'm watching the movie "Who am I - no system is safe" to learn German. the contex is:
Wenn ich gewusst hätte, wie all das ausgehen wird… hätte ich alles anders gemacht.
I've read a post about this How to know which form of "all, alle, allen, aller, allem, alles" to use? but still not clear for my case. My understanding is:
1) alles - everything, express an genreal idea about something. Is that correct?
2) all - i'm not clear in this. pls explain why they use all in this sentence?
3) Any tip for me about this specifice one - all? I understand about declination but still totaly confuse in this.
Thanks for your help,
