After reading about their four, ahem, five demands for 'normalization', at this point even just gestures of goodwill are doing more harm than good. This is just setting the bar for how they expect their prisoners to be treated as next time, even as they continue to slit the throats of our own.
Col. Babu and his Jawans committed a despicable act of ambushing a negotiating party, then torturing and slitting prisoner throats. It was a shocking act. Not characteristic of a professional army, but a gang of degenerates.
The PLA reinforcements at Galwan probably had the greenlight to fight to kill. But perhaps they had never expected to overperform. Col. Babu is killed, and his Jawans were routed. So many Jawans died trying to run away. Their own Indian Army were too terrified to come rescue them. The PLA just had to take pity on them. Not because of weakness, but because the PLA have a firm humanitarian tradition. While the Indian Army had nothing like that. They are more well known for carrying out a hospital massacre than doing humanitarian work.
After Galwan, India dared not hurt anymore PLA prisoners. When 2 MIA PLA soldiers were captured by the Indian Army late last year. China demanded that they be returned to China unharmed, and India complied without much fuss. I'd like to think that that happened because of the shame of seeing the enemy being better men than themselves. But we all know that's not how the mind of Indian military men works (forget about the Jai Hinds and Bhakts). They don't respect goodwill, they only respect power. So I believe they did that because of two things. First, the terror from the trauma of the Galwan rout. Second, the fact that dozens of Jawans after the battle were captured, under the mercy of the PLA. That is power, and that spooked them. If the PLA wanted to, they could have just as easily tortured, and slit their throats too. The Indian Army will be powerless to save their own Jawans if the PLA decided to give it back to them. Worse, India is in no position to go to war with China. I believe that it is this humbling experience of being on the business end of real power, that compelled the Indian Army to start behaving themselves ever since.
