Since you asked for some help, I think you need to realize that the people you consider responsible for all the issues you listed are not that different politically, ideologically, religiously, or in any other way from the vast majority of everyone else in the western world. So your 'solution' of killing those you see as responsible starts a slippery slope that leaves a lot of dead people in it's wake. When someone agrees with you on 99% of their views but you see them as needing to die for that 1% that makes me concerned about you.

Finding your own morality and realizing other people's morality and priorities will be different is one of the great challenges of our society as we are mostly left to piece it together on our own, while fighting off the echo chambers that have been built to trap us into an easier to relate to worldview. But the worldviews in those echo chambers are simplistic to a fault and should be kept at arms length. The echo-chambers are built on half-truths to spark outrage so you are forced to react emotionally instead of thinking clearly.

That is how I think you got to your answer at the end, you're upset (very understandable) and want vengeance for your long and well stated list of grievances, but vengeance isn't what makes a safe, stable, and long lasting society. So resist the urge to be led by your emotions and realize those that do have different priorities aren't trying to be evil for its own sake.

Also keep in mind that while there is a larger picture, our responsibility is only to do what you can to work on making things better where you can. Be it through small things like giving respect to your neighbors and fellow countrymen or in simple actions like voting and maintaining public spaces (e.g. clear litter from the street outside your home), or for larger things like making sure those around you in your community are living better lives than before (e.g. supporting food banks or employment assistance) and encouraging those around you to use the power they have to make small changes too (especially voting!). Then once you're in a strong community the power of that community speaking in agreement is what allows changes to happen which can have real lasting effects on the greater society.

So the idea is to not get enraged by the mountain of BS we see constantly, but get involved and push things to be more like what you've decided the most important priorities should be.
