The habit of adding modern concepts into Scripture is very common.
It's something we should guard against.
While an argument can be made that cremation "promulgates violence against the human body", the point cannot be biblically supported.
Cremation while generally not the usual practice of the Israelites, it occurred in rare instances;
An example is the gathering of Saul and his sons after their death, mutilation and humiliating public display by the Philistines in 1 Samuel 31:8–13.
“all the valiant men arose and went all night and took the body of Saul and the bodies of his sons from the wall of Beth-shan, and they came to Jabesh and burned them there” (1 Samuel 31:12, ESV 2016).
The "valiant men" of Jabesh-Giliead (see 1 Samuel 11:1-11) expressed their gratitude to Saul by rescuing their decomposing remains and carrying them out of enemy territory.
The cremation of their bodes was not a sign of disrespect or dishonor, as indicated by David's grand commendation in 2 Samuel 2:
“David sent messengers to the men of Jabesh-gilead and said to them, “May you be blessed by the Lord, because you showed this loyalty to Saul your lord and buried him. Now may the Lord show steadfast love and faithfulness to you. And I will do good to you because you have done this thing.” (2 Samuel 2:5–6, ESV 2016)
Burial practices vary from culture to culture according to the situation at hand:
Such as burials at sea where the bodies are released into the sea;
In the future, as the sci-fi genre imagines, bodies would simply be ceremonially released into deep space.
