He wasn't insecure even as a child going by his origin story if I recall tried to have Mufasa killed so he could become king. He was a true egomaniac obsessed with power. He was consumed by Envy and Pride not insecurity and never shows strong hints (or even small ones that I recall) implying otherwise. Jealosy =/= Insecurirty. Being emotional only adds depth it doesn't mean they can't be Complete Monster they just can't show redeeming features like true compassion, protective, mercy, sympathy/Pity, true insecurity (here) etc. He hasn't shown any of those positive emotions towards others that we know of.
