I was rooting for Thanos the entire time.
I suppose it depends on how you look at it. From Thanos' perspective, it was justifiable.
Yes. I think his ideas for the future were good. He changed the world for the better and he wanted to destroy death because she was such a burden to everyone including him.
You have a good point and it's cool that you can see things from a different perspective, especially if the idea is outside of the norm. I bet there are some fans out there who agree with your thoughts on the topic.
I hate it when other people disagree with me. They are idiots and just have to learn to suck it up.
I understand feeling frustrated when people disagree with you, but you need to respect their opinion. If you want people to consider your opinion and listen to your reasons, then you need to respect their opinion if they disagree with you. That way, you can have an interesting and useful discussion!
