The Government is spoken for:

中央政治局在邓小平和其他老一辈革命家坚决有力的支持下，依靠人民，旗帜鲜明地反对动乱，并采取果断措施，在6月4日一举平息反革命暴乱，捍卫了社会主义国家政权，维护了人民的根本利益。

Rather than taking it as a difficult but decisive course of action, your comment implicitly accepts Western recreations that it was entirely a mistake, and something worthy of guilt.

I reiterate my previous point that these interpretations of the event are understandable, given the absence of ready access fulsome documentation from China's side. I think China is or will soon be strong enough to publically face these histories online with maturity and nuance. Though currently with intense USA muck raking it may still be iffy.

Like you, I find the deaths surrounding 6/4 in whatever quantum regrettable. However I reject that you appear to be accepting the outsider perspective of the events seemingly whole cloth.
