No, the Russian Federation is one of the main beneficiaries of this war. The more people die in this massacre, the less the world looks at the atrocities that the Russian Federation is committing on the territory of Ukraine - the same mass murders of civilians, the use of prohibited weapons, theft of children, extrajudicial executions, executions of ethnic Ukrainians.
Theoretically Russia could play some role if acted in a good faith, since Russia has close ties with Iran and Hamas, but from history we know that Russia is not ending conflicts, but ignites and fuels them. In current conflict in the Middle East Russia has primary stake, as this conflict diverts international attention from Ukraine, where Russia itself is an aggressor and occupier. So, it is more reasonable to think that Russia could have a role in fueling this new conflict in the Middle East.
The intervention of the Russian Federation in the events in Gaza has been ruled out at the present time, as the Middle East is an American area of influence, so its intervention will allow the United States of America to directly intervene in the Russian-Ukrainian war
