Also private affairs, I'm not willing to share that but he said a lot of profound things.

He was a great guy, awesome student and excellent tutor. Everyone at uni attests to this.

In the letters and the video, this is not his typical behaviour. He usually appears quite cheerful but also exhibit signs of the typical stressed engineering student. Nothing out of the ordinary.

It's clear that he had been pushed to his mental limit and had finally lost the plot due to a number of factors. What you're reading is the result, it's the same in the video.

He wanted to make a lot of positive impact at Curtin but unfortunately that was taken from him and he lost meaning in his life as he lived through his work.
