"There was no lead-up to his decision and the writers didn't give us enough of a glimpse into what was going on in his mind when he did decide to join Pike."

To start off, he was suffering from PTSD after the events of S2. Not only that but he had to massacre innocent people because his ally (Lexa) left him and the rest of his people to die. Echo, somebody who he thought he could trust, betrayed him. She allowed Azgeda to kill even more of his people, including his girlfriend. His judgement was clouded because of his very bad experiences with the Grounders and the horrors he went through and watched the people he loved go through in S2. All of these things combined led to his mental breakdown. In my opinion, he is exactly like Finn in S2. If you think about it, they both seemed like they were trying to hold back from committing their massacres, but in the end, they just couldn't stop themselves. Finn when he was stepping on that one Grounder and Bellamy when he very briefly argued with Pike as to why he wouldn't get him the guns. I don't think Bellamy's actions should be excused, but I can bring myself to feel sympathy towards him. Regardless, I can see why he joined Pike but at the same time, it did feel a little bit rushed.
