Yes, on sleeping bag. Alaskans freeze to death all the time, especially in the mountains in April. Bring a jacket. Bring a first aid kit. Bring an ice axe if you are climbing  a mountain because people save their lives every day with ice axes. There are a hundred ways to get hurt in the bush that are more common than bear attacks. Your pack would weigh a thousand pounds if you planned for every contingency. Bear attacks make morbid news but they actually are very rare.  It doesn't make the news when somebody has a sleeping bag and comes home safe. It doesn't make the news when somebody saves themselves with an ice axe. Yet, it happens every day. This rarely makes the news but it's a fact that every mountain climber understands. 

You can blame the bear if you want but that is the point of my first post. To feel safe it helps to blame  someone or something, whether it's a bear or the victim.
