At the end of Avengers: Infinity War,
Thanos' plan comes to fruition as people begin disintegrating, including Bucky Barnes, Drax, Groot, Mantis, Maximoff, Parker, Quill, Strange, T'Challa, and Wilson.
Could this be caused by Thanos' direct manipulation or does it happen without Thanos' interaction but as some random event?
The heroes getting disintegrated, was it because it was Thanos's choice to complicate the possible regrouping of the Avengers/Heroes or was it just random?
