Insanity Check: Simba Congo

[Augenis]

So, if the Simba rebellion were to somehow succeed and take over Congo in the 1960s, how insane would their government be?

I'm not asking for how long they last or if it is even plausible - just on the level of crazy that the dictatorship would exhibit. If you want, you can compare it to other OTL crazy dictatorships for an easy measurement.

For those unwilling to read, here are a few excerpts from the Wiki page to set the mood:

The majority were young men and teens although children were not unheard of in the conflict.[15]

Because of the range of political beliefs within the Simba's attributing an ideology to the rebellion is very complex. Whilst the leaders claimed to be influenced by Maoist ideas, Che Guevara wrote that the majority of the fighters did not hold these views.[16] The fighters also practiced a system of traditional beliefs which held that through correct behaviour and the regular reapplying of Dawa (water ritually applied by a Medicine Man) would leave the fighters impervious to bullets.[17]As well as Dawa multiple sources, most notably an eye witness account from members of the US Consulate staff in Kisangani, note that the fighters would often be under the influence of a variety of illicit substances as they went into battle.[18]

As the rebel movement spread, discipline became more difficult to maintain, and acts of violence and terror increased. Thousands of Congolese were executed, including government officials, political leaders of opposition parties, provincial and local police, school teachers, and others believed to have been Westernized. Many of the executions were carried out with extreme cruelty, in front of a monument to Patrice Lumumba in Stanleyville.[20]

At the behest of accompanying Shamans, many Simba warriors had even discarded their firearms as a way of purifying themselves of 'Western' corruption. Many had been given a magic potion (dawa) by officers that they were told would ward off bullets and subsequently charged headlong into the ANC force.

The rebels started taking hostages from the local white population in areas under their control. Several hundred hostages were taken to Stanleyville and placed under guard in the Victoria Hotel. A group of Belgian and Italian nuns were taken hostage by rebel leader Gaston Soumaliot.[25] The nuns were forced into hard labor and numerous atrocities were reported by news agencies all over the world.[26]

Sooo?

Wouldn't it have a good chance of succeeding if they had continually gotten more and better Soviet aid, while at the same time (however implausibly) the Western powers backed off from doing the same on their OTL scale?
