A conclusion I find politically inconvenient? You have no idea what my politics are, please stop projecting. To answer your question though, no, they should not be lumped together because they are not the same thing and so the mitigations would've/could've/should've been different. In other words, lumping all these things together as "caused by COVID" is the opposite of useful. For example, you do better next time with deaths due to COVID in your system (category "a") by ramping up vaccination faster/better facemask policy/earlier lockdowns/etc. You can decrease category "b" by having more hospital beds / more healthcare capacity. You can reduce the deaths in category "c" (seemingly suicides) by having lockdowns that aren't up-and-down rollercoasters / better mental healthcare / etc. All of these, though being "due to COVID" should be handled very differently so it is counterproductive to lump them all together. Again, I think you might be projecting a bit here, because the only reason I can think of that you would want to lump them together is to push a political agenda. Not for any utilitarian reason.
