To add to others here, anger is neither good or bad. It is an emotion. It is okay to be angry at people causing pain and suffering. It’s how you deal and use anger that matters. As others said, let it be energy to create positive change and don’t allow it to burn you out from the inside.
So allow yourself to be angry, to feel the hurt and to be sad. Then do the work to make the necessary changes to make the world better.

Back in my reddit days, there was a guy who did AMAs about vacuum cleaners that was actually incredibly informative. After talking and analyzing many machines, he suggested s couple vacuums. For my needs we got a Miele canister C1. It wasn’t cheap, but 8 years later it is doing very well. No fancy circuit board, straightforward, solid manufacturing, 8 year warranty, a dial controller for the suction. No problems at all. Probably will last another 20 years. It’s a great machine and has paid for it by not needing replacements. The closest thing to a complaint is that I wish the cord was about 1.5 -2m longer so I didn’t need to unplug it to change outlets 2/3 of the way through, mostly because I’m lazy.
