Lets be real tho, this little rant was very good and I'm not gonna delete it just because thats not what the anon was actually tlaking about! So, to anyone who thinks that without Mal, alina would have ended up WITH the darkling (not LIKE him, which is what my anon actually said... again... sorry!!!), this is for you!
..... okay but... how does that translate to her ending up with the man who abused her, manipulated her, groomed her, enslaved her, sexually assaulted her, tried to kill or did kill many of the people she loves, sold a dear friend of hers into sexual slavery, killed her mother figure in front of her and made her look at her dead body (uhhh joffrey parallels much?), and literally only viewed her as a source of power for himself?
Also, the reason she wasn't lonely in the orphanage was because she was friends with Mal. It's made pretty clear that he was basically her only friend growing up. She never mentions any other kids at the orphanage that she was close with, she never remembers any other kids from the orphanage as companions or friends, they repeat over and over that it was always just the two of them against the world.
And lets not forget, the reason she didn't end up being sent to the little palace when she was like 12 or younger was because of Mal. She hid her powers from the Grisha testers so that she could stay with him. If he hadn't been there, they would have discovered her as the sun summoner when she was a little girl, and they would have sent her to the palace. Imagine the Darkling with total and complete control over a 12 year old Alina? He would have had so much more power over her, it would have be so easy for him to manipulate her and groom her into being under his control. He would have enslaved her as a little girl and used her to destroy the world in his image, and he would have succeeded. Mal being there saved not only Alina from being sent into the Darkling's clutches as a pre-teen, but also saved the whole fucking world!!!
Whether or not Mal was around, Alina would have never, ever ended up with the Darkling. He never loved her, he was never romantically attracted to her. He is her ABUSER!!!!!! Everything he ever did and said to get her to believe he was on her side was in furtherance of his abuse of her. He spent every single second they were together lying to her, manipulating her, invading her privacy, stealing from her (her letters AND Mal's letters, and in the show, her journal and her drawings), and grooming her. If Mal wasn't around, it would have just meant there was nobody around who cared enough about Alina to protect her from a 500 year old shadow douche bag who wanted nothing more than to control her power for his own personal gain.
So, no. If there was no Mal, she wouldn't have ended up with the Darkling. She would have ended up as his slave at 12 years old instead of being able to withstand his manipulation and abuse long enough to escape him and fight back. She would have ended up just like Zoya, a tool in his arsenal who has been abused by him to the point where the idea of loosing his favour turned her cruel, who didn't see what kind of a monster he was until he killed her family without a care in the world. Or worse, she could have ended up like Genya, sold and abused for the Darkling's personal gain because he saw her as nothing more than a trinket in his possession to use at his own discretion. Without Mal, the Darkling gets Alina's power, he gets to destroy everything in his path and kill anyone who stands against him. Without Mal, the Darkling wins. Without Mal, Alina ends up as nothing more than a slave.
