People outraging on this movie should understand something. Stop trying to find moral messages in a fictional movie. Second thing - it does not glorifies toxic masculinity but portrays it how it can destroy lives.
The movie itself is a caricature of a fool who involves himself passionately with everything he comes across. In order to develop the character in the movie, there are some scenes foreshadowing the future of kabir Singh in the movie and they had to be deeply disturbing, misogynistic, alpha male portraying bits which ultimately throws kabir in a downward spiral destroying himself. Hurting and pushing away people who loved him.
If you think kabir Singh is the hero of the movie, you didn't get it. Kabir Singh is the villain, a toxic liability, passionate fool who is a black hole attracting every single entity around him just to destroy their life.
Getting inspired from this movie is like getting inspired to get kicked in the balls multiple times while hanging by the nooze.
