Terrible moves that defy explanation

From two recent games.

Missing tactics I can understand. Being a noob and not developing your pieces I can understand. But some moves are somewhat mysterious. How do they even enter player's heads as candidates?

1) Weakens two pawns, particularly the backward pawn on open file.

2) Removes my doubled pawns, helping me create a passed pawn.

3) And again.

4) Trades active c1 rook for passive f8 rook as well as gives up the c file.

5) Deactivates his best piece (knight). Ignores his worst piece (rook), opens lines for my pieces into his position.

6) Trades his most active piece, but more importantly gives me a monster passed pawn. d2, Bb2, Rc1 is now unstoppable.

There are moves the systematically dismantle their own position. These are the moves I'd pay them to play if I were trying to get them to lose on purpose.

A couple of those were the move I wanted to play when I saw the position.

Well ok, to be fair, maybe the first thing a person thinks when they see, e.g. Qd3 in the last one, is "can I take the queen? Lets check"

But it's just so utterly horrible. 100% of the good things that result are for black. 100% of the bad things for white.

My engine?

No, they're moves that I instantly knew were bad when I saw them, and I couldn't understand why someone would choose to play them... although after posting this topic I realize I'm being a little harsh and beginners make much worse moves then these.

Maybe this will help some players gain insight, because these moves are bad with zero calculation necessary. Only logic is required (and valuing things like piece activity and not weak pawns).

If someone wants to talk / analyze one of the moves in particular let me know. I tried to give a brief explanation for why they're bad in post #2.

@sammy_boi a lot of lower rated players only look at how they think the move will benefit them, not the potential drawbacks or weaknesses that it creates.  That was a big problem for me as I was learning chess, especially when it came to pawn moves that weakened squares

Good point, this is very true.

Yes, it reflects poorly on the tool.

By the way engines and UCIs are free.

Not that engines are great in these situations, but FWIW at depth 36:

Not that this really matters. Rxc8 doesn't make sense. It's a move you can reject no calculation necessary.
