Did Thanos know about Hela ?

Hela In Thor Ragnarok (2017)

Thanos in Avengers Infinity War (2018)

Hela's durability, though incredible, can only handle relatively smaller attacks, such as bullets and Mjolnir 

Thanos is also much better than Hela in terms of combat skills. In terms of speed, both of them are almost the same 

Hela has some pretty explosive powers. As mentioned earlier, she half-succeeds in giving life back to Thanos 

Thanos has all six Stones, and thereby controls the entire universe 

She can also literally kill someone by touching them 

Thanos is one hell of a mighty fighter, the MCU version of Thanos will be defeated by the MCU version of Hela 

She can create energy blasts that can kill Gods, travel across space and time 

The powers of the Infinity Gauntlet are almost limitless, and this extreme power would certainly allow Thanos to easily defeat Hela
