Agreed, equating them is just penalty inflation.

A more productive focus would be:

1. that those who have been shown to accept bribes are actually removed from their position prosecuted successfully.
2. Transparent governance with independent watchdogs so that corruption is harder to hide.

Treason carries the death penalty in a lot of countries. But in most countries treason is poorly defined in law so it’s difficult to say whether somebody actually did commit treason from a legal point of view because it’s difficult to define what treason is.

Oftentimes it’s just easier to fire them on bribery charges and prosecute them using the standard peace time legal standards.

But it’s useful to call it treason on national television for PR reasons even if they never actually face treason charges.

*This is generally the case for most countries I have no idea how Ukraine defines treason.
