Yes, Thanos is consistent and if you suspend your disbelief and take his basic plan as logical, everything that follows makes sense. Consistently stupid, but that was the fig leaf that made Infinity War 2 billion dollars or whatever.

I could see there is some kind of pathway where A (muh kids) might lead to B (whatever happened there) for Scarlet Witch, but in addition to the weird idea that she might be sort of justified, the escalation was way too fast. This is a character that ostensibly had a sound mind as of Endgame. What MCU writers think of as a "motivation" is actually an excuse to smash action figures together.
