Thanos from Avengers: Infinity War was a pretty damn good villain and although some have understood his actions in the film (sorta), it’s pretty clear that what he did was horrid. In Guardians of the Galaxy, it was revealed that Thanos was behind the murder of Drax’s family. In Infinity War, not much is explained on how this happened but thanks to Infinity War‘s director’s commentary, we’re offered a little more insight as to how it happened.
The Guardians of the Galaxy film provides us with the tragic backstory of Drax played by Dave Bautista, explaining that Ronan the Accuser slaughtered his family, fueling rage and vengeance in Drax. Holding a knife to Gamora’s throat in Guardians, Drax described the heinous act by Ronan saying,“Ronan murdered my wife, Hovat, and my daughter, Kamaria. He slaughtered them where they stood. And he laughed!”. It was only near the end of the film did Drax realize that Ronan was a mere puppet serving under the Mad Titan, Thanos.
It’s clear that Thanos is now Drax’s primary target and in Infinity War Drax sees his chance, when sneaking up on Thanos and The Collector in Knowhere. There is a much more significant meaning to this as revealed in the home video commentary by Joe, one half of Russo Brothers director duo:
“This is a callback to Drax’s history with Thanos here… His planet was treated the same way as Gamora’s planet. Drax was put on one side, his family was put on the other.”
That’s pretty deep man and it gives a much more elaborate view of the cosmic exploration of the Marvel Cinematic Universe. The MCU does have some questions and answers that are often times explained by directors in the end so maybe the director’s commentary is the best way to fill in the gaps. Granted, it would have been better if it was properly explained in the films but whatever.
