I'm not about to engage that Russian troll like you are (life's too short), but his citing the UN recognition of 14K deaths is on its own misleading.
Per that paper (bit.ly/3D6XEsv), civilian casualties had decreased from 162 in 2018 to just 44 in 2021, a few months before Russia invaded. These are country-wide numbers, not necessarily caused by Ukraine.
And of those 44 casualties, only 7 were actual deaths, the rest were wounded.
Per the bottom of p.2 of the UN Paper, there were 8 civilian deaths in 2020, and 7 in 2021.
Fifteen deaths in two years, and we're supposed to believe that Russia's invasion was motivated by a desire to save lives? The same Russia which has caused tens of thousands of deaths in the #UkraineWar since its invasion, including indiscriminate bombing of civilians? The same Russia which covered up the separatists shooting down a civilian airliner?
