leaving chapter 20

In the begging Jonas is freaking out because his fathered released a baby and Jonas doesn't want to go back home so the giver let`s him stay and they eat then the giver talks about Jonas leaving and something like that and the giver is staying because so everyone in the community won`t kill other people.  My question is that when Jonas finds this thing will everybody be able to see color and feel emotions (of course they will).  My reaction is that I`m glade that Jonas is leaving and finally changing the community
